Re: Men in black... Judicial tyranny strikes again
No, no, no...
Anthonyp, when I wrote the following:
...that is also why there is more brake pad material on the trailing shoe? (A way to tell them apart.)
I was
not referring to a difference of
thickness of the brake shoe pads. I was referring to the length (arc length) of the brake pad material.
Look at this pic:
Front of vehicle and "leading" brake shoe is at picture left. Note how much more the friction pad material of the "trailing" show wraps around the axle. The "trailing" shoe has
more square-inches of friction pad because the pad is longer (in degrees of arc) than the pad on the "leading" shoe.

On the contrary, I've rarely owned a vehicle where the pads wore evenly front and back. Your front and rear brakes are different animals, and take differing amounts of stress.
True -- Depending on which automotive writer one selects as an "authority," the front brakes provide 65% to 85% percent of the vehicle stopping power. (When you hit the brakes, the vehicle nose-drives and there is a weight shift. The rear wheels are unloaded and the front wheels are more heavily loaded.) In the days of yore -- yore meaning the days of drum-brakes on all four wheels -- it was a commonplace to replace the front drum brake shoes twice for each change of rear drum brake shoes.

That's why you often see Drums in the rear and discs up front.
False -- Disk brakes replaced drum brakes primarily for two reasons: (1) Disk brakes are an inherently superior design not nearly so subject to the phenomenon associated with drum brakes called "brake fade." It would take a lot of words to explain "brake fade," and I won't go into that here because it would only further muddy the water. Another day another thread. (2) Vehicle builders know that the production line assembly-installation time reguired for disk brakes is much less than drum brakes. Build a million or so vehicles and that time saving translates into big-time cost reduction and big-time increase of productivity.
A historical aside: Disk brakes and anti-lock disk brakes were used on large aircraft long before use in automobiles.

Yes, and I believe the reason the front shoes are wearing faster than the rear is because the front of the wheel has to stop before the rear of the wheel does. Or it could be a bolt in the flywheel......<sniffle>......
HAHAHAHAHA! Now cut that out, Sparky! :lol:
