Rear brakes wearing before front?

I have 34k miles on my truck. Yesterday while at the service department, the service manager calls me and says my rear pads are just about gone while I still have some pad left on the front. If that's the case, why are my front pads always dusting the worst?

I haven't had a chance to look but I smell BS!

unless there is wrong with your trucks' braking system, the rear should never wear before the front. Take a look, if they are right, get the shop to fix whatevery is wrong. then replace the pads.

Proportioning valve may be out of adjustment, causing premature wearing of the rear brake pads. I would question whether this may fall under warranty.....

Having the rear pads wear out first doesnít necessarily mean you have a problem with your braking system. This doesnít seem to be too uncommon with these trucks. Iíve read that a lot of people have the rear pads wearing out before the fronts do. It all depends on the quality of the pad and the material. From personal experience Ive done rear brakes on cars/SUVís that have about 30K and there were no problems with the braking system.

Just make sure your wheels spin freely and there is no scoring or glazing on the rotors. Otherwise I would just put a good quality brake pad on the truck.

I'll be checking it this weekend. I'll report back with my findings.

I beg to differ with you on that opinion. Also, I have seen some comments were Ford on the later model F150s, put more emphasis on the rear brack.

On my 2006 F150, 5.4, 3.73, SC, which has 72,000 miles, and 64,000 of those miles have been towing, the rear rotors/pads needed to be replaced at about 35,000. The front just needed pads. I tow swiftly too.. I cruise at about 80 mph with a 7x14 enclosed trailer with 4 bikes in side. The brakes always work. But, the rear rotors went be for the front. In fact, I still have the stock rear rotors on. Should be replacing them shortly.

Just my two cents from experience.

ceh-You are soo correct, I have owned many cars and trucks in my life (and quite a few new ones,even F-150's) and they have all worn the front pads out 1st. Not so with the '04 and up F-150's. Don't know what it is with these trucks but for most people they definitely wear the rear out 1st. I wish someone could come up with the engineering reason for this (not just theory)

all pick up trucks do this. a front wheel drives brakes are dristributed approx 85% front 15% rear. fronts will almost always go first unless the rears see alot of mud/dirt. a rear wheel drive or 4x4 truck is 60% front 40% rear. not to mention how much smaller surface area the rears have and how much dirtier they get then the front. the rears almost always wear out first. normal

Somethings up, this is not the first I've heard of rears going before fronts so don't wave the b/s flag just yet. Have a look first and judge for yourself. All I know is my front to back replacement ratio is almost dead nuts 2:1. The backs just got replaced for the second time around 200k km's and I'm due for my 4th set of fronts very soon. I think Ford put more bias to the back brakes that a) have a larger rotor diameter, b) a narrower surface and c) a weaker caliper on a smaller pad. Now it's like you HAVE TO replace all 4 brakes at the same time.

Been lurking for awhile and figure this is a problem common to me as well. It would seems to me that with all the technology out there, Ford would have solved the uneven wear problem by now. I thought the proportioning valve was supposed to distribute braking action between front and rear?
I have a 98 F150XL w/ 160k on it and am looking at replacing my front disc pads again soon.

Not B.S. My 05 screw got to metal on rear about 5000 miles before my fronts. Guy at Advance said one reason was back was smaller, and I agree . They were a good bit smaller. Boyd

Same here. I just replaced my back pads and I have some life left on my front pads. I thought it was because a I tow a bunch.

Your back brakes will wear faster if you do a lot of highway driving also.

Just replaced the rear brakes on my 04 2wd screw at 45,000 miles. Fronts are still original and the pads have a ways to go before they'll need replacing.
