Oooookay, how am I supposed to inspect Disc Brakes?
When you check your disc brakes, measure the thickness of the linings on the pads so that you can tell whether the linings on your brakes are badly worn. If the lining is down to the thickness of the steel backing plate, the pads should be replaced. To check disc brakes, follow these steps: Jack up your vehicle and remove a front wheel. Jul 28, · Accurately checking the wear on your brake discs is not quite as straight forward as checking the pads but you can do a basic visual inspection where most major issues should be immediately apparent. The things you're looking out for are deep scoring on the braking surface of the disc or uneven wear caused by metal on metal contact with worn pads, radial cracks often caused by .
Checking the remaining brake pads is the first step for a brake maintenance. In now case of the disc brake system, the play of the lever or pedal does not change unlike the drum brake system even if the brake pads are worn, so it is important to visually check the brake pads directly.
It is better to check dosc brake disc at that time. The brake disc may be damaged more than expected, depending on the compatibility with the brake pads material and the usage environment, so be careful for what is the cause of pancreatic cancer. In a disc brake system, not hhow the brake pads are worn but also the brake disc.
The degree of wear of the brake disc may vary depending on the material of the brake pads. Check brakw unevenness of the brake disc surface with a metal ruler. Let's check not only the brake pads but also the wear of the brake disc when performing a regular check of the brake how to check brake disc wear. When the brake pads wear to about half the thickness compared to the time when it is new, the wear speed of the brake pads is faster.
If sandwiching the brake disc only with the back plate of the brake pad, after all the friction material of the brake pads is gone, fheck only the brake system will not work properly, but also the brake disc is abnormally worn and becomes unusable, so it is necessary to pay attention to the wearing of the brake pads. Regular maintenance of caliper piston and replacement of brake fluid are very checkk for the brake system so that the same brake work and brake touch can be obtained at any time regardless of the season and weather.
If you are cautiously paying attention to the brake, you can avoid the worst-case scenario of the "iron plate brake" where the brake disc is pinched by the back plate. The wearing speed of the brake pads is different when they are new and somewhat reduced. If the friction material of the brake pads pasted to the back plate became thinner, the volume of the friction material and the heat receiving capacity decreases, and the heat radiation also reduces, resulting in wear of friction material.
In other words, the wearing speed of the brake pads increases after wearing out a certain amount. If you miss and neglect to check the remaining wear amount of the brake pads thinking that, "Since it's still about half of the remaining thickness compared to a new one, it can be used on the same distance", the brake pads will be the minimum wearing thickness with unexpected speed, or the wear of the pads may be known for the first time by the sound of the metal that sandwiches the brake disc with the back plate.
It is better to check the wear amount of the brake pads at the same time while checking the wear amount of the brake disc. The brake disc is made of materials such as stainless steel, cast iron, and carbon. In the commercial motorcycle, stainless steel brake discs are used, which do not rust in rainy weather and provide cneck power even at low temperatures.
Considering the relationship between brake pads and brake disc, many riders or mechanics think that the only thing that will be reduced is the brake pads, and the brake disc can be used for a long time. However, in reality, the brake disc will also be worn out just like the brake pads. The aggression against the brake disc depends on the material of the brake pads. In general, organic brake pads that is baked and hardened plastic components is less aggressive to the brake disc, and the sintered brake pads using sintered metal has better-stopping power, but it will wear the brake disc more than organic brake pads.
The two major factors of brake disc wear are: 1. How to check brake disc wear with the brake pads, 2. It depends largely on brwke usage environment. The compatibility is related to the how to replace a blinker of the brake pads.
The sintered brake pads used metal for the material is more strong stopping power than the organic brake pads using plastic material, but the damage to the brake disc is bigger. Besides, gravel and dirt are splashed together with rainwater on the brake disc, and brake caliper hod the brake discs together with gravel and dirt, so riding a motorcycle in the rainy weather is more vulnerable to damage than riding a motorcycle in the fine weather.
If the brake pads and brake disc are worn at the same time, the how to check brake disc wear of the unevenness on both worn out surfaces will match. However, since the new brake pads have a smooth surface and less area in contact with the worn brake disc, it cannot be obtained sufficient stopping power.
how greenhouse gases contribute to global warming in the case of some aftermarket brake pads, since the shape of the friction material is slightly different from OEM brake pads and the contact area with the brake disc cannot be sufficiently secured, the stopping power may be lesser. Just like when the brake pads are worn, the worn brake disc accumulates braking heat because of reduced heat dissipation efficiency, which can cause cracks in the case of deformation or perforated brake disc.
For this reason, many brake disc surfaces are engraved with the thickness of the wear limit indicating the service limit, and if the thickness of the brake disc, measured with a caliper or micrometer, is less than to that, replace the brake disc.
To determine the actual life of the brake disc, the thickness of the area where the brake pads are in contact is important instead of the thickness of the outer edge. Place a metal ruler from the center of the brake disc to the outer circumference, and check the unevenness chck the contact surface of the brake pads.
Measure the number of dents on the front and back, replace the brake disc if the wear limit has been reached. However, depending on the contact position between the brake pads and the brake disc, there is a case where the thickness of the outer peripheral portion is less than the wear limit, the inner portion may be largely reduced.
Furthermore, since the surface of the brake disc is sometimes worn in a wavy shape, it is better to check the brake disc how many years ago was the eiffel tower built putting a metal ruler on the brake disc unless you are sure by looking at your eyes.
In the case that the brake disc has small scratches like a record disc, it is understandable that the motorcycle continued to how to check brake disc wear in the state where gravel was sandwiched between the brake pads and the brake disc, such as in rainy weather.
The perforated brake disc has a hole to improve the draining properties of the brake disc surface, which is effective for braking in rainy weather, and it is better to wash the dirt of the brake disc to avoid scratching after riding especially on rainy season.
Also, if it is a piece of solid brake disc instead of a floating type of brake disc, it may be possible to flatten the unevenness of the surface by polishing with an internal combustion engine shop, so it is better to consult a professional mechanics. If the brake cbeck wear, the brake discs also wear. Make your choice based on how you use your motorcycle and your braking preferences, whether to allow the aggression to the brake disc by giving priority the goodness of the brake performance or using brake pads that take into account its life span.

Oooookay, how am I supposed to inspect Disc Brakes? May 24, 1. I thought the dust shields on the newer Freightliners were bad enough. But our newest trucks use disc brakes ummm, Yay!? The first thing that caught my eye was that the air cans are almost perpendicular to the wheels. Also it seems like there's some sort of dust housing on these brakes too.
I have no problem checking brakes as part of my PTI obviously but there's got to be a more realistic way to inspect them than pulling off all the wheels every morning. Tips anyone? I'll probably go to the manufacturer's website later today too. I'm just not sure if they're Bendix units or Dana's and I'm not at work right now. Infosaur , May 24, Coffey Thanks this. Name Email Phone Yes, let employers and TruckersReport text me with new opportunities, job alerts and other career information to the number I provided.
There is no charge for this service, but standard message and data rates may apply. May 24, 2. I got put into a new truck its a mack.. TruckerPete , May 24, May 24, 3. They developed the standard for inspection of air-disc brake inspections. I don't have a copy handy and since we don't have any so equipped I haven't bothered to learn the procedure.
Sublime , May 24, May 24, 4. In the shop we use a lighted telescope mirror,poke through the holes in the wheel and you can see the pads. No way to see other than pulling the wheels.
No adjustment except initial. Do check that the drain holes in the brake cans are either all open or at least the bottom one,some got through with the top open and then they collect water. May 24, 5. Just use your brakes as normal. When you can't stop no more, it be time fer some new'uns. Coffey , JReding , Wingnut1 and 6 others Thank this. May 24, 6. I was thinking the same thing when we got our new trucks with DISC brakes..
It's seems as though it's very hard to find information on the internet It's not a common thing you can find the information about how to check the components.. Not only is it time consuming it's just not practical.. Since the brakes are more effective when they are heated unlike drums which are the totally opposite if your brakes are working great at start-up then they will be way more effective as you motor down the road It's hard to inspect them because of the dust caps in the way..
There is no adjustments on these brakes because that happens as the rotor heats up and all parts are internal in the caliper They have outline the CVSA requirements for disc brakes.. Which is kind of hard to believe considering there needs to be some time of outlines that people can follow to check these brakes safety. Some sort of guideline as they have with the drum brakes Right now it just seems like we are going "blind" into the world of disc brakes.. We know they are safer and give us far better stopping distances..
Plus now you will be able to feel brake wear in the brake pedal much like a car where as in drums you cannot tell brake wear by the feel of the brake pedal.. Anyhow on with what I have found on the world of the internet So how do you check this stuff when you can't really see it This is the million dollar question Upon my reading I heard of a tool that would slide in from the back and I guess it would contact the disc or something and you would measure this to know pad thickness..
Is everyone going to be carrying a little measuring tool like that?? I doubt it Also there isn't a standard side thickness of pads as well among different manufactures , and even within the manufactures different models etc I can't believe how hard it is to get information about this. It's like pulling teeth.. I hope I at least helped out a little bit.. I provided a link to the webpage I went to..
It's got 5 pages of different OOS criteria on it RubyEagle , scythe08 , NW can man and 1 other person Thank this. May 24, 7. But ifn u wanna believe our KW sales manager--"these pads on these here disc brakes will last at least k!
May 24, 8. May 24, 9. May 24, When I had a truck with disc brakes, I went through two inspections, on each the inspector just noted "disc" in the brakes section, neither one of them checked anything with them, just kinda skipped over it.. One was in CA and the other was in NV.. Even the CA inspector told me not to worry too much about them, since there's nothing as a driver that we can do with adjustments of any kind.
