So I recently replaced the front brakes on my 3.8L 99 Mustang. The driver side caliber needed replacing due to unknown caused damage. So I replaced that, But it seems like the passenger side rim is alot hotter after a drive and there is alot of brake dust, there is some brake dust on the driver side as well but not as much as the passenger side. I know brakes have a brake-in period but I've already drove it for 200+ miles. So what would you guys suggest I do? I'm thinking on taking it into a shop to have everything double and triple checked.

 

Do you hear any rubbing? You might need to replace your caliper. Your caliper MAY be getting stuck somwhere in its travel and not positioning itself right.

 

I replaced the one on the driver side, the passenger side looked fine. I don't hear any rubbing, but it has the brake dust smell and alot of buildup on the rim and the rim gets hot to the touch.

 

The rim itself gets hot? Sounds more like a wheel bearing then brake problems... do you hear a slight 'roaring' sound while driving? Might be hard to hear over the exhaust But if your rim is getting hot that sounds like a wheel bearing more than anything. Simple fix. If you have the time, Pull your tire off, then move your caliper out of the way. Once that being done, just lay the tire back onto the posts and see if you can spin it easily.

 

But would that create all that brake dust tho?

 

Maybe, depends on how bad of shape the wheel bearing is. But also it could be that and the caliper both. I honestly am unsure

 

The excess heat could be a few things. Bad wheel bearing, sticking caliper, misaligned front wheels... the list goes on.

A sticking caliper isn't always the calipers fault. It could also be a clogged/collapsed break line not letting the fluid back up into the master cylinder and not letting the pistons retract in the caliper. Could also be the slide pins that the caliper slides on are damaged/rusty/worn not letting the caliper slide smoothly. If it is the caliper, you can just rebuild it by replacing the seals inside (which is all a remanufactured caliper is). Its fairly simple to do and the rebuild kit only costs about $10.

Good luck...

 

Unfortunately it was a sticking caliper and I was traveling at the time where it got perma-stuck. So I had to have the closest dealer fix it....ugh.

 

Glad to hear you got it fixed at least...
