What is going on with my brake?

[Motorhead350]

My back left brake pad seems to be leaving only half the mark on the disc... maybe even 1/3. I showed this to Ken on the way back and he mentioned that the pad didn't ware correctly and a new one was needed.

What I would like to know is how this happened, what to do to prevent it and if I need to cut the rotor. I think I can get a new set of pads and brush off the rust, but I need to be sure.

Again I don't get this. How in the world would only 1/3 of a pad make contact with a disc?

When I installed my new rear pads, I noticed they did not sit 100% flush with the rotor but my stock ones (147k) where at the same slight angle and wear angle on the pad as the new ones are sitting at.

Good question Dom.

The pistons aren't pushing the pad far enough out in one spot.

So this could be a bigger problem then I thought? I might need to replace the caliper and pads?

Well let's not get all crazy. Does the car pull to either side when you hit the brakes? Losing fluid? Pedal go to the floor? Steering wheel shake when you stamp on the brake pedal? If no to these, don't even worry about it.

Check the way the caliper is mounted and the slides.

+1

My old Bronco would sometimes get the caliper stuck in the slides so that it actually only wore 1 of the 2 pads on the caliper. Imagine my shock when I saw that.

:eek:

The car stops just fine, the disc just looks weird.

What should I just replace the pad?

I would ignore it haha. Front brakes do the most braking.

You would think but the rear brakes do play a big roll. I've had a pulsing in my brakes for a long time and just thought it was the rotors warped again. Changed out my rear brake pads, pulsing stopped and have more brake feedback now. I still plan on replacing the master cyl cause I have too much travel in the pedal compared to what it was like when I bought the car.


So what if the caliper is actually mounted at a slight angle? Cause I remember perfectly how mine were when I took them off and put them back on and there was slight angle before and after. They've always been like that for as long as I can remember, I'd check the pad amount every 4-5 months while the caliper was still mounted.

So the pad needs to be replace regardless I take it?

Replacing it will only result in another pad looking the same way.

Should I change the way it's lined up, mess with the pistons? Can anything be done. I am confused again. :o

Turn the caliper around after you replace the pad.

That's what I figured.

Say WHAT? :eek:

Do to the age / mileage and use (or abuse) you've reported in the past, I'd replace the calipers & pads. Good time to flush the brake system out.

I realize that, but I changed all pads and discs this past spring. That is why I am wondering what went wrong. I should have mentioned this at the beginning. No racing at the track this year either. :confused:

Maybe it's was just a faulty pad. That's the best I can think of.

LMAO!!! :rofl:

Wow it took me an hour to get this one. I think I need more sleep. :o

you may want to check your tightening sequence, and be sure to titen them all down with the same ft.lbs. And actually, you can take the rite rotor and put it on the left hub. Learned that from "Billy Jack"......... "I'm going to put my right foot on the right side of your head,...!!!!!SWACK!!"
