Is This Normal W/New Brakes?

2009_370z · 09-03-2015, 01:08 PM

Hey guys,

So a few weeks ago, I upgraded my brakes with some slotted rotors, SS brakelines, pads and fluid. In the morning when I go to work, the first few minutes of driving the car, when I fully press on the brake pedal, my brakes make a really loud noise but then stops later on. Is that normal? Is that part of the break in period?

Thanks.

Did you bed your pads? If so, how? What compound are you using? Many more questions.

Shouldn't be happening.

No, I didn't bed my pads. How should I do it?

Does that mean I bought faulty parts or who did my install did a bad job?

Bedding New Brake Pads

1. Make sure all parts are installed correctly
2. Go for a drive on a road without other motorists
3. Accelerate to 60, brake with moderate pressure down to 20 mph
4. Repeat step 3 approximately four times
5. Drive home without further hard stops
6. Allow brakes to cool overnight WITHOUT using the e-brake

Thanks for this!! I'm going to do this and see what happens.

Is there any surface rust on the rotors when you first get to the car in the morning? If there is then that is most likely the cause. Initially you're grinding off the surface rust which is causing the noise. Once it's gone the noise goes away.

Check the pads, make sure none were installed with backing plate against the rotor.

zefaulter · 09-04-2015, 06:55 AM

I've heard you can sand the pads a little too instead of doing the drive

efuseakay · 09-05-2015, 11:11 AM

Before you bed them in, do as POS said. Double check to make sure the pads weren't installed with the shims against the rotors.

Why no e-brake? Isn't it a separate drum/shoe system? Or has my memory gotten worse than I thought?

gomer_110 · 09-05-2015, 09:38 PM

It is a separate system but it's still a common rotor/e-brake drum used by both. That's one block of iron that's hot and needs to cool without picking up an uneven friction material deposit.
