crazy brake wear on rear brakes
A friend of mine keeps bringing her 2003 Accord V6 to me to service the brakes and I've come to the conclusion that the rear brakes are badly hooped. In less than 60, 000kms I've replaced the rear pads 3 times and each time I've replaced them they've worn out like no tomorrow at just 15, 000-30, 000kms.
I've done the following when replacing the pads:
1. Machine rotors so they're true
2. Use factory Honda rear pads
3. Cleaned and lubed up all slide pins
4. Cleaned up the pad holding brackets and shims
5. Used anti-squeal spray on backside of pads
6. Bleed out the brake fluid from callipers
7. Properly inboard pad alignment pin with groove in calliper piston
What I'm seeing is crazy uneven wear of the bad. The only thing I can think of that is causing her issues is the bracket that holds the pad may be a bad casted piece from factory. When installing the pads the bracket is EXTREMELY tight. So tight that I have to use a hammer to tap or force the pads into the holder bracket. In doing so I would imagine that the pads can't move freely enough in such a manner that when she's applying or not applying the brakes that the pads are essentially jammed and wearing out a lot faster than normal.
I've done many civics, MDXs, Odysseys and other cars and not one of them had pads that fit so tightly as this 203 Accord does.
I was thinking of replacing the calliper mount/brake pad bracket with a new one from Honda but they don't sell the bracket on their own.
I'm sure someone here has seen a similar issue?
Thanks for any suggestions you may have.

Re: crazy brake wear on rear brakes
If the pads are tight in the bracket like you're describing they wont last. When I used to work for Honda we'd grind a little off the sides and ends of the pads where they fit in the holder so they would move freely.

Re: crazy brake wear on rear brakes
The issue is that the bracket I think is where the problem lies.
Is there a way I can effectively grind off part of the pad holder set to make this a permanent fix?
Thanks

Re: crazy brake wear on rear brakes
You're going on right track. I wouldn't cut/grind any parts UNLESS that's a MUST. Couple things that ring in my head is this two
1. Misadjusted parking brake cables. If the parking brake cables aren’t adjusted right, they can affect the volume of fluid that’s needed to apply the brakes. If the brakes don’t apply evenly, they won’t wear evenly.
2. Light brake application. Applying the brakes very lightly can put the whole braking load on half of the braking system. Repeated stopping with one caliper and one rear brake can wear that diagonal faster than the other.

Re: crazy brake wear on rear brakes
I have an '10 accord and did research on the accords before I bought it. From '03 to current there is some sort of defect that causes the rear breaks to wear fast. I replaced all rotors with drilled and slotted rottors, replaced the pads with ceremic and have had no problems with mine.

You might want to read this link. It describes what needs to be done, to service brakes in Canada (snow areas). Good luck
