Re: 1999 GMC Jimmy Rear Brakes
Hi: Weird problem... 80% of braking is done by front brakes... check them first to make sure they are functioning properly, use copper coat on slides... it is not unusual for brake pads to ware unevenly, probability that both rear axles are floating is pretty unlikely. Hope this helps... please rate suggestion...ty
Check the axle end play. if there is significant axle in-out motion, this will cause excessive inside pad wear. it will also cause the caliper to bind under breaking conditions, yet slide freely when there is no stress applied

Where do you live meaning if you live on mountain or driving down steep incline every day you will ride brakes every day.that will wear on them a lot.use manual low1 gear coming down mountain.also buy a good brand brakes .i learned a long time ago if you pay more .it will last more.longer.

yes baby it to him and replace both calipers and rotors as they will work better with your new brake pads. Do Not Do a half a job when it comes to brakes. its your family you are dealing with. calipers are cheap rotors are cheaper and pads are also cheap. its 3 hours labour to do a complete front brake job and rear brakes take 2 hours. with new shoes turn drums replace wheel cylinders and new rear brake hardware price in Canadian for front brakes under 400 price for rear under 250 American parts prices slightly different but labour times the same
it is really common for the rear caliper slides to become stiff or frozen. The caliper should slide back and forth with little effort. If it doesn't than make sure the slides are free and lubricated.
If you had a difficult time installing the new pads into the bracket than that could also be the problem. The pads should fit into the bracket with little effort and feel loose once installed. If they don't than remove the shims and clean the rust from under them. Then reinstall the shims and see if the pads slide a little easier in the brackets.
Lastly make sure you didn't pinch or twist the rubber brake hoses.
Another thought is to remove the caliper from the bracket and try to spin the rotor/hub by hand. Maybe the e-brake shoes are causing the problem?
Rear brake shoes as fitted to drum brakes can typically last up to 60k miles with periodic adjustments, but you have rear disc brakes and the shoes will typically last half of that.
Also, modern brake pads no longer contain asbestos and are now made using harder metallic compounds; the direct result is that brake discs (US=rotors) are also considered to be consumable items as they are worn down by the harder pads. It's not unusual to have to replace front discs every other pad change and rear ones with every pad change; in both cases the mileage will typically be around 30k miles on most models.
Hi... to adjust rear brakes providing the shoes are good... just drive vehicle in reverse and pump brakes... rear shoes are self adjusting so they should "adjust" themselves... after doing this test by putting on park brake, put vehicle in drive and see if vehicle moves forward, repeat procedure if necessary. Hope this helps... please rate suggestion.... ty
your inside pad wore out first do to a bad caliper or frozen slide or brake hose.remove brake hose off the caliper and see if you can turn the wheel.if you can replace hose and bleed caliper.if wheel still doesn't move buy a loaded caliper,this will come also with new slides!and then bleed
hi from the uk not too conversant with your model ? BUT here in uk the same type of rear calipers for hydraulic disc brakes and a seperate set of brake shoes operate the park brake/s which is internal of the rotor ?? thebrake shoes will have an adjuster manually adjustment when rotor/drum is in place ? so if you look at the area between the top of shoes you may see a threaded rod with a serrated round wheel which when turned on thread will move shoes out one way and in the other ? so to fit rotor you must rotate this wheel so shoes close up enableing to fit rotor/drum over shoes easily ? then secure rotor with screws?? if fitted then you adjust ppark brake shoes by turning with a flat screwdriver via a hole which is/should? be in rotor and will turn in line with this adjuster? tighten brake on then turn back notch by notch till rotor turns free or just? do this b4 you fit the disc pads then repeat on other brake assy on other side? re assemble discpads and pump brakes till hard this then leaves the park brake cable to adjust if req'd if so pull p/brake it should come up approx 4 or 5 clicks to fully lock of brake this allows for what is known as reserve travel left on cable to apply as brake shoes wear ok? hope this helps?
Hi joelalthomas, if they replaced your brakes and you never even made it home they had better warranty the work and as for the "it was a common problem on 2002-2004 trucks" well check for Chevy recalls as this is a safety issue that would have been corrected at no expense to the vehicle owner, do a little more research my friend and let me know what happens, I will check around a little as well in the meantime I would find a new garage.Do not pay any more as you said your brakes worked fine until they worked on it good luck to you As for your 4x4 did you look at the left side when you did the right side? and were they bled off properly? you can visually check to see if the calipers are functioning
