Rear pads wearing faster than front?

[bderks]

I last replaced the rear pads on my 97 CE about 18 months ago, then installed 100 series pads in the front 6 months later. Last week, I started hearing the tell-tale squeal from the rear - sure enough, the pads are already toast. I checked the fronts while I was at it, and they're still at about 75%. What could be causing the rears to wear faster than the fronts? Vehicle is not lifted, and I go easy on the brakes. Any ideas?

Ping Scamper - I found this post about your 97 CE with the exact same problem:

Did you ever find the cause of the problem?

Oh, and CDan - you have a PM regarding some new rotors!

Brandon,

Did you remove the 3rd row seats? If so, that lifted the rear so you should adjust the LSPV.

I'm thinking it's possible that both front calipers may not be in the best shape.

The function of the LSPV is that it automatically compensates for variation in rear vehicle weight. So I wouldn't think it would be necessary to readjust it due to removing the seats.

Duhhh. Yes, that's correct and I can't believe I suggested that. Musta been late at night.

Brandon,
18 months on the rear ~25k miles for many people. That's not too bad for OEM rear pads if that's the case.

Beo - let me ask you this: I do tow a boat frequently, would the extra weight in the rear cause the LSPV to increase the amount of rear braking? If so, that may be the culprit.

25k per set of pads? I guess I expected more. My 01 Dakota I had before went 65k before changing pads. But it also dropped 2 trannies by 50k....

Cheers,
Brandon

Yes, more bias to the rear when more weight is in the rear.

Same problem here

25000 miles after a complete dealer brake job: pads, resurface rotors, bleed brake fluid - rears at 20%, fronts at 60%. Dealer says probably the way the resurfacing was done on the rotors plus they are very thin. Otherwise unsure why the premature wear. I checked the rear load sensing proportioning valve and appears OK, * EXCEPT * -- is the rod that is attached to the rear axle and the valve itself supposed to be straight? My appears to have a bend in it - which didn't look right to me. I had the shocks replaced a few months before the brake job and I'm thinking some numb-nut might have bent the rod wreching the the shock brackets off. What do y'all think?

No, it is supposed to have a bend. Some will advise you to change that bend when readjusting the LSPV for a lift. I believe the best practice is to make the adjustment at the location where the valve bolts to a bracket at the frame.

I wonder if the dealer checked the LSPV ?

There are some good posts by Rich on how to setup the valve and it's in the FSM I think. If you are still having this issue longer term then I'd have the LSPV checked according to IH8MUD and the FSM.
