4 Wheel disk brake question

[ACoyle]

Do the disk rear brakes wear as fast as the front disks, as slowly as the rear drums did, or womewhere in between?



Thank You

AC,



It's usually somewhere in between, but more towards the drum brake end of the spectrum. The more weight in the back the more they will wear.

Most 4 wheel disc brake system the rear wear as fast or faster then front. I'm not familier with the system on out trucks but usually the REARS are a differant pad compound(softer)and usually the rear pads are SMALLER. Had a neighbor who put 141k on a 03 3500 SRW and brakes were wearing even on all four at time of trade in. They were close to needing replacement(all four)

I cut my 4 rotors back after Thanksgiving and put on Bendix pads (the factory ones were horrible). Now about 10K miles later, they are all warped, big surprise, but the fronts still look smooth, while the rears are worn alot. I was pretty surprised at that, obviously the rears work harder than I though they would. Probably put on 2K miles hauling 2 or 3 sleds, and the rest highway miles. The hauling part is a little scary, the Engineers designed the Dakota brake package to be good, not overly great empty, but she's a little scary with a load, thats part of the reason I'm in the market for an HD Ram...

Rear pad matierial is usually softer then front. smaller also. The reason rotors warped in 10k is eaither driving habits or those Bendix pads. I found on most if not al manufactures the factory pads for the most part better in wear and stopping then most aftermarket pads. I put factory pads back on everthing I own. Aways have.

The rotors warped because you had them turned down. Rotors are a heat sink, that requires mass, remove the mass(turning) and you increase the likelyhood of warping. Besides that VERY few brake lathes do a good job, or is the operators



Lots of guys turn rotors, I NEVER do, they are too cheap and too important to mess with. BTW, a pad change does not necessitate resurfacing rotors. I change between street and track pads on the Porsche all the time with no problems.



My experience with the 3rd gen trucks is that the rear brakes last about 40% longer than the fronts. I can check on actual milages for replacement on my trucks if you like.
