Evening scoobynetters,

As title, I had the dealer fit my new brakes, which involved new rotors and performance friction disks, also new pads.

I started to brake them in, and noticed that under hard(er) braking car pulls left and right, it happens when I break from higher speeds, like 60 or more.

I also saw a bit of smoke from right pad, and right disk felt a bit hotter.

Is this normal and would go away after some more braking, or there is a problem ?

Appreciate any feedback

 

It sometimes happens to me too, not much though, and has in most cars I've owned, on the odd occasion - but 98% of the time it is fine. Although I've only recently had new pads fitted, but it did it before this. Seems to be quite common but if happening all the time and much worse after having some work done then I'd take it back to the garage to get them to sort it out for free until it's sorted out. Could be a geometry issue?

 

Well, with the original brembo disks I never had this problem, even when I put on those new pads. On the track pressed it very hard even at 120 miles and still no pull in any direction.

Now I also hear the rotors/disk, when breaking from 60+ they make a kind of "drrrrr" noise.

I left the steering wheel untouched to see what happens, and could see a slight move of the steering wheel to left-right a few times

 

sticking caliper piston??

 

calipers wont be sticking if brembos or unlikely, if they are 4 pots then highly likely

 

Jack the car up and rotate the wheels to see if there is anything obvious.

Ideally the garage fitting them would have done so using a DTi gauge and ensured all was well before letting you drive off.

 

Thanks everybody for the input.
Had a chat with the garage and they suggested to have the system checked for air leaks, so they will try that, hopefully will cure it.
