Red Hot Glowing Rotor Rate Topic: -----

If you were a registered user, you would not be seeing this!

My 93 spirit has been having this problem for awhile now. I first noticed it when I let my foot off the gas I instantly start to stop and my front driver side hub cap melted. I took the wheel off and my brakes where worn down to nothing on the driver side so i replaced the caliper, pads, and rotor. I get the same thing, a hot wheel and my car doesn't roll or coast. This goes on until driver side pad brakes and destroys caliper #2 rotor #2. I replace caliper, rotor, pads, and wheel bearing hub and this rotor is still getting hot. My cv boot is completely shredded and all the grease leaked out. Could the cv joint generate that much heat to make my rotor hot. Could my brake lines be messed up. I'm saving for a new car but this piece needs to last a little longer. THANKS A BUNCH!!

Probably not the C/V.

The problem may be the bearing. If it's bad the rotor will not be at 90 degrees to the caliber and if it's cocked a little it will rub without pedal pressure.

The other possibility would be a bad hose on that side. If the inner lining of the hose is bad it could accept pressure but not let it flow back to the master cylinder on the side with the bad hose.

When you find and fix it, you must change all the brake fluid, as it is completely ruined from overheating. Even if the bearing is not the issue and the flex hose is, the bearing is probably toast, given the rest of the damage.

I would have stopped driving it altogether before it got to that stage. The dragging and the smell would have been positive warning not to go further.

You have an inner and outer brake pad, as you know. Are they worn down evenly? If so, the hub (thus both rotors that you replaced) is probably still in alignment. If it were at an angle, you'd have seen strange wear on what's left of the pads and rotors.

I second the faulty/collapsed flex hose issue. I had a similair problem with my Daytona and new flex hoses solved the problem. However due to the amount of overheating you likely have other issues now.

Thanks for the replies. The pads are wearing evenly. I'm going to try and replace the flex hose and get a new boot over the cv joint and re grease it.

I replaced the flexible brake hose and it works great...thanks for the advice. I also replaced the steel line that goes from the flex hose to the "metering valve"? Only because i broke it trying to disconnect it, but it works great...I can coast and i dont have to jam on the gas to accelerate. Thanks again.

And you bled the brakes all around right? Otherwise there's trapped air.

Might even save a little gas. If it pulls toward the side with the new hose under heavy braking, do the other side.
