Totally glazed over my rotors! Now what? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

OK I've posted this problem about my ebrake never working right, it won't lock the rears, it takes 10+ seconds to fully lock, etc, etc.

I took it over a friends house to have the ebrake cables swapped out, he takes off the wheel, and says "Ummm I don't think your ebrake is the problem, your rear rotors are totally glazed over".

I'm running cross-drilled and slotted Brembo rotors front and rear, Project Mu Type NS front pads and Mu D1 Spec rear pads.

Now I'm not sure what to do at this point. Do I need all new rotors and pads? Or just rotors?

Why the hell would my rear rotors be completely glazed over if I'm using street brake pads? I thought that only happened with crappy pads.

And whats the best way to avoid this happening again? I have no idea how the hell my rotors got like this to begin with.

Get them turned/cut? I'd at least try that before you go spending the money on new rotors. Also, did your friend check the pads to make sure they weren't glazed over as well?

were the rotors zinc coated? did you let let the pads break? I've heard stories of people having problems with the coated rotors but don't know how true they are.

maybe its the rotors? get blanks and try that out.

Make sure that your e-brake is disengaging completely. You could glaze the rotors if you just drove around for a little while with the e-brake engaged.

have them turned with a non-directional lathe, can help prevent it.

If you want to try it, a die grinder and an aggressive scotch pad (I think the correct name) can be used to deglaze and give them a non-directional finish.

Scuff up the rotor with sand paper and see what happens

They were zinc coated and you can't turn/cut slotted-cross drilled rotors.

Not sure if the pads were glazed but I'm buying new ones.

what does glazed rotors mean? what does it do?

Prep Guy · 05-16-2005, 11:29 PM

if you get chemicals on your rotors like grease and the friction makes it all blinged. your rotors and ur pads become slippy so friction is limited so your brakes arnt griping.

are you leaking anything in that area?

Nope.

Somehow the rotors got glazed within a few days after installing my pads and rotors because my ebrake never worked since then

Did you use the brake cleaner before you installed the rotors? They have a coating from the factory so they won't rust while in the store.
