Brake smell

**trans-am nut** · 11-01-2008, 02:57 PM

Hello I have a 2002 WS6, and I have been noticing that the rear brakes have been smelling lately. I took them apart and cleaned everything and put it back together but the smell persists. I looked at the E-brake and it does not appear to be worn, but the back rotors are starting to have a blueish hue to them. Has this happened to anyone before?

Caliper pins may be stuck not allowing the caliper to float
Pistons may be sticking not allowing the pads to back off
Master cylinder or proportioning valve may be so full of mung the pressure can't bleed off when the pedal is released

Take them out & grease them or free them up
Use a C-Clamp & see if you can push them back into the bore.....make sure to suck some fluid out of the master with a turkey baster beforehand
Bleed the hell out of them to try to clear the system

You might want to try driving it like you normally would then jack up the rear end and see if you feel it dragging before you tear into it.

Will I need a scan tool or anything? I hear that a brake light might appear if I bleed the system without a scan tool. I greased the slide pins and checked the e-bake yesterday and i'm still getting the brake smell. Thanks for the help.

Shouldn't need a scan tool unless you let the master go dry and suck a load of air.

Do the wheels spin without exerting too much effort??

They will spin about one to one and a half turns.

Just throwing an idea out there but if you have an m-6 clutch material smells the same. BTW when you spin your rear tires put the car in neutral. if you can spin them freely then something is jacked up.

i have the same problem with my 98 camaro ss. but sometimes it smells and sometimes it doesnt. the smell smells like electronics are burnt up.

could be your clutch glazing over...
