well i have a week with my new brakes changed rear drums for discs, also swaped to ss lines, installed slotted and drilled rotors and some axxis ultimates all around...

my quetion is, how long should they take to settle in, also i feel a slight vibration and the end of braking (when speed is about 20 mph or less), could the rotors be lose?

also my system had a lot of air, i mean a lot, we bleed the twice and there was still some air coming out of the lines, we didnt bleed a third time cuz it was kinda late, what can cause so much air to be in the brake lines??

also when installing my pads the rear piston was a bitch compress could it be cause no fluid was in them? i had bought them several months back and didnt install them until now....

i would have it checked again to be sure, but there is a break in time.

vibration during braking could be rotor/pad run-out. try getting your rotors resurfaced. bleed the lines again, you dont want ANY air in them at all.

So even if the pads and rotors are new, the rotos could need resurfesing?

are slotted and drilled rotors resurfacable? sorry for the n00b question...

You have ABS?

Are these slots and holes cast in? or machined in? If they're machined, you probably feel all the slots and holes, which is causing the vibration.
If you bled them twice and still have air in the lines, you're either not bleeding them properly, or you have a leak.

Yes my car has ABS, so it would be a good idea to have them resurfaced...

just was thinking is it like a little quick shimmy in the pedal when you hit the breaks?

Try gravity bleeding over night for your air in the lines issue

and check that all your components are on right and "tight"

Are these discs new?


No it could cause damage to the bit
