Brake problems

[DJDannyB]

I have fitted 266mm brakes to my furio, I fitted them with brand new mintex pads & discs. After the had bedded in, i noticed they were warped as whenever i hit the brakes the car shook like mad! So i was told to replace just the discs as the pads were quite new. I have done that and they have been bedded in, they are a lot better than the mintex ones were but they still do feel warped and shake a bit if i hit the brakes hard. I took out the pads the other day to rough em up a bit to take the glazing off them and see if they would flatten and i noticed that there are bits of the pad broken off, why would this happen?

Basically, do i need to replace the pads aswell? Or do i now need to replace the discs and pads again?

When you fitted the disks did you use a dial test indicator to check for run out?
Did you make sure the mounting face on the hub was clean?
I tend to clean it up with a wire brush.

As above. If there is a grain of anything on the face then it will put the outside edge of the disc off by mm's

[DJDannyB]

No i didnt clean up the hub face, i just put some copper slip on the back of the discs. So its not my pads then?

the pads would just wear back to flat mate take off disks and clean it all up and see how that goes

[DJDannyB]

gonna try that mate, hopefully sort the problem out! might buy a refurb kit for the calipers too.

just try cleaning the pads and see how it goes

Give them a good clean mate might fix everything !

howlong did it take to notice ? cheap discs warp easily im guessing s youve upgraded the brake size youve been giving them a harder time and leaving it later to brake maybe its just not a good combination of disc nd pad for your driving style. although how are the 266 brakes worth the buy ?

How long did you bed the pads/discs in for, and did you do it properly?

Never heard of decent discs like Mintex's warping - are you sure they weren't already damaged when you got them?

[DJDannyB]

They were brand new and sealed no visible damage at all. Maybe i hit the brakes too hard when i was bedding them in? ive kept them though so ill give them a try when it comes too new brakes again. May of been the pads, seem to be better now i have sanded them down a bit

[lharrowing]

mintex do a set that are pretty muc standard replacements so arent going to be amazing might have just been a bad batch of them or something.

check disc run out before you leave it too late and damage them.

i bet theres shit behind the discs as said above.

you wont hurt them bleeding them in!

[DJDannyB]

What is disc run out? They have been bled
