mcali6301 Posted March 5, 2015 Report Share Posted March 5, 2015 My car just finished it's 60K maintenance. The rear brakes are moderately worn (more than the front) and I am concerned as to why. They did not report any other issues. I was trying to figure out why this may happen and I remembered that the car has a feature where the brakes will stay applied when the car is stopped on an uphill (to prevent rollback). Would this have anything to do with it or should I be concerned that there is another issue.. Quote Link to comment Share on other sites More sharing options...
macbwt Posted March 5, 2015 Report Share Posted March 5, 2015 I would assume that all the brakes are applied not just one set front or rear with the feature you are describing. My 2011 has the same feature, but I am unsure if it would just be the rear brakes. Seems like it would be all the brakes. Interesting but I do not have an answer for you, but will watch to see if anyone else does. Quote Link to comment Share on other sites More sharing options...
ls973800 Posted March 5, 2015 Report Share Posted March 5, 2015 The brakes would not wear down just because they are being used as a "hold" on hills. In order for the pads to wear, the rotors would have to be moving and the pads then applied against them. When sitting, the rotors are not moving and the pads are acting as a clamp. Soon as you start to move, the pads release. Quote Link to comment Share on other sites More sharing options...
akirby Posted March 5, 2015 Report Share Posted March 5, 2015 All modern cars are showing faster wear on the rear brakes nowadays. Several theories - 4 channel abs, stability control, etc but it's normal. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted March 5, 2015 Report Share Posted March 5, 2015 (edited) From reading around the net, using the rear brakes first/more was a conscious design decision to prevent nosedive in hard braking/emergency situations.

macbwt Posted March 5, 2015 Report Share Posted March 5, 2015 Why the extra wear on the rears? I am guessing it is how you drive and the driving patterns. Tons of city driving may cause the rears to wear more and light driving with lower traction could cause the rears to employ more often causing the extra wear. For me I am all highway so I guess I tend to wear the brakes less but use more front brake due to the higher speed and sometimes hard/shorter stopping distances comparitively. Best answer I could come up with based on some short research. Electronic Brake Force DistributionNewer cars use the antilock brake hardware and the onboard computer to replace these proportioning valve systems with a system called Electronic Brake force Distribution (EBD) in order to distribute the exact amount of pressure at each wheel to insure a balanced brake system.

With 4 channel ABS it's easy to change the bias dynamically and I could see the benefit to using more rear brake to prevent nosedive. My Lincoln LS did this with suspension geometry - you could slam on the brakes from 60 mph and it would stay dead level. But that expensive aluminum suspension was one of its downfalls.
