Brake Noise Pinpointed

[Blackzze]

Hey everyone,

the brake noise is caused by the discs building up a rusty 'scale' on the surface area. This is caused by : Moisture in the air, and is more pronounced by either having cold/moist conditions, and/or leaving the car for a few days.

This can happen literally overnight if it is wet!!!

All it needs to clean the discs is a decent drive :D :D

Unless you change the discs to a different make, it will keep happening, and its down to the steel toyota uses. You will notice many brands of cars dicsc seem to "rust up" very quickly, and it is just one of those things. Even changing discs is no sure measure, as some "rust up" and some don't.

The reason it is more pronounced in reverse, is that the pads wear in a 'foward' direction, so reverse would make more noise with the scaling on the disc cos the pads are going against their natural direction.

I have it as well, and it is just "one of those things".

your are correct blackzze,

once the brakes warm up and the pads brush on the discs the noises go away. B)

Thanks for that, i was also told by a mechanic to blast some water into the rear discs when washing the car just to clear any gunk in it which might also be contributing to the noise.

Yeah. you're probably right. when i wash my car and get suds on the rotor, it rusts up right away. Hmmm.

[Blackzze]

I always blast arount the front/rear calipers to get rid of any gunk in there, I don;t know if it helps, but it can't do any harm :D

Yeah, it's most annoying when I wash my car and I have to wipe my wheels twice because the rusty water from the discs drips down and makes them dirty again ! Especially the fronts that are ventilated

[Blackzze]

IZZ-FE,

Nice signature, do you leave your melways and water at home when your going to the drags???? hope so, the extra weight (even in the stivo) is a killer :D :D

[CAP]

Nah I leave them on the backseat for better weight distribution when cornering even though it hampers my acceleration :D

But I've found my fat cousin does a better job :D :D
