GaPrix Posted March 20, 2013 Report Share Posted March 20, 2013 So my front inner pads have both worn at nearly 100% the rate of the outer front pads? I noticed my car was starting to stutter stop occasionally so I pulled everything off for a look and the inside of the front rotors are pretty nasty, the slotted wear design is 75% gone indicating their done for. The outside of the rotors and outer pads are fine lots of life left. What could cause this? Quote Link to comment Share on other sites More sharing options...

GaPrix Posted March 20, 2013 Author Report Share Posted March 20, 2013 I was thinking that, but since both driver/passenger happened to do it had me questioning it. I know I greased everything last I changed them. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted March 21, 2013 Report Share Posted March 21, 2013 What type of lube did you use for the slides? Also, how often do you lube the slides? Sent from my iPhone in some random spot of Texas. Quote Link to comment Share on other sites More sharing options...
GaPrix Posted March 21, 2013 Author Report Share Posted March 21, 2013 I used some synthetic brake caliper grease, I put new pads/rotors on in the summer of 2011 maybe 2010. Quote Link to comment Share on other sites More sharing options...
BS009 Posted March 21, 2013 Report Share Posted March 21, 2013 Have you already pulled off the calipers? Do they move freely back and forth like they should? Check for corrosion in the bores of the caliper bracket side of the slides. Was there still a lot of grease on the slides after removing the calipers?

GaPrix Posted March 22, 2013 Author Report Share Posted March 22, 2013 (edited) Have you already pulled off the calipers? Do they move freely back and forth like they should? Check for corrosion in the bores of the caliper bracket side of the slides. Was there still a lot of grease on the slides after removing the calipers? They appear to move normally, there was a thin coating of grease left. And I got the wrong rotors, these are 286mm, should have been 267mm. I didnt see that at first, They are listed as both for our vehicles (front), so i'm guessing theres a caliper bracket that can be used? Edit - I figured it out, 95/96's had 286mm, thankfully I happen to have the 96 assemblys, which will go on the car over summer. I guess I didnt really waste money on the larger rotors.

GaPrix Posted March 23, 2013 Author Report Share Posted March 23, 2013 Changed out the rotors with some autozone blanks, heres the strange thing. The pads were okay overall, one pad was more worn than the others but they were still good. The rotors however were extremely worn on the inside only, I'm somewhat confused by this.

Silentkillzr Posted April 8, 2013 Report Share Posted April 8, 2013 Slide pin sticking or something sounds like. Mine used to wear all sorts of weird from slidepin issues. Quote Link to comment Share on other sites More sharing options...
55trucker Posted April 8, 2013 Report Share Posted April 8, 2013 I would suggest that you pull apart the fronts assembly and look inside the brackets to see if the bushings are corroded to the point where the support bolts for the calipers can no longer move back & forth in them. The calipers themselves don't slide on the bolts, the bolts slide inside the bushings, which are in the bracket. While you've got everything apart also check each of the pistons to see if they are free in their bores. Quote Link to comment Share on other sites More sharing options...
DavidHowell3633 Posted May 30, 2013 Report Share Posted May 30, 2013 A mechanic explained to me one time that he has seen some hoses that have a portion come apart inside the hose allowing fluid to flow in one direction down to the claliper only. As the rubber ages and becomes brittle, the internal piece with only one end attached now serves as a one-way valve of sorts. This would cause some fluid pressure to remain in the line from that point to the caliper and cause uneven,excessive wear on the inside of the rotor. I personally have not cut open any old rubber lines to verify. Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted May 30, 2013 Report Share Posted May 30, 2013 I have uneven brake wear from slide pins all the time lol Sent from my Galaxy Nexus using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
GaPrix Posted June 5, 2013 Author Report Share Posted June 5, 2013 Alright so one of my rears apparently got stuck too, I put new brakes/rotors on the rear last year...I know I greased them good, time for all new calipers? Ridiculously annoying. Quote Link to comment Share on other sites More sharing options...
