Uneven Brake Pad Wear
Saturday, November 28, 2009 12:31 PM
My inner driver side brake pad has worn down to the squealer, but the outside pad still has more than 50% left on it.

Any suggestions?

I know it could be a sticky caliper, and I don't think that i wanna rebuild one myself, just for the safety issue. So before i go out and buy a rebuilt one, is there anything i can do now to try and fix this?

Also, my rotors are in decent condtion as well, i'm getting those re-finished. I've had these pads on for about 1 1/2 yrs.

For now i'm going to clean out as much as i can and grease everything up. Can those rubber seals around the piston be taken off and re-used? it doesn't look damaged.

Sounds to me yes you got a sticky caliper. Is there any pulling or anything while braking. Also I would take a look at the brake lines front rubber brake lines, I would look into those been replaced if they are old as well.


Good Luck.

That would be the Bolt and pin (sliders) and hardware (isolators):

#1 - Bolt & Pin
#2 - Hardware

The bolt sleeve gets dirty or rust causing the caliper not to slide. The hardware (isolators) get dry rotted or sticky preventing the caliper from sliding. Replace them and lube them wit some grease to keep them moving freely.

Just happened to me. Its the sliders and bushings. My sliders were ok but the bushings needed replced and greased. Seems fine now.

Thanks for all the info guys!

I'm in the process of finding a rebuilt caliper now. I've been getting quotes for $80! I'll keep looking for a better deal, if they are as cheap as some say they are...

There was no pulling while braking, and my rubber lines are ok.

Great diagram btw Mad Jack.

I would look at NAPA for the rebuilt calipers - and if your not looking for performance brake pads they have "loaded" re-manufactured calipers that have the new hardware and pads already assembled.

Just unbolt the old caliper and bolt on the new (and bleed) and your good to go!

Also I use wheel bearing grease on the caliper pins, seems to work well. Also I've used anti-seize and it seemed to work fine as well.

For some reason I never see grease on pins, whenever other people/places do brake jobs, no wonder they stick!

Very true Jack.

I have never taken out the pins to grease them before, so like you said, no wonder they stick.
And i've changed the pads and rotors twice...yikes...

I wish it was easier and safer to fix the existing caliper. It seems like such a waste to buy new ones just because of some dirt. But once again i don't want to take any chances with brakes. I do plan on trying to rebuild my old one anyway and testing it in safe conditions, but for now aftermarket will have to suffice....lame.

Upon further inspection i decided to just grease everything up and try it again with new rotors and pads. brakes feel much better now (obv new everything) but i'll pay close attention to the wear patterns to see if my calpier is doomed for replacement.

Might as well buy a new caliper. I know for a fact you can get one for less than $20 at Oreillys.

I live in Toronto, i don't think there are any oriely's here. I know if i search hard enough i wil find it

Pads seem to be wearing fine now, it's still a little early to tell, but I'll run it like it is for the winter.
