View Full Version : New brake rotors?

02-08-2009, 07:19 PM
I purchased four new brake rotors and when I tried to install the rear rotors I could not compress the brake piston in far enough no mater what I tried.
Is the answer as simple as getting the new rotors cut? Or am I missing

if you was able to get the caliper off most brake calipers on back the piston turns in a certian direction to get compressed back i cant quite remember but if it is like this then you have to turn it one way maybe this will help m,aybe you can get more replies on this good luck:thumbsup:

I cant remember right now if the 99 cobra got the rear vented rotors or the solid GT rotors. you need to make sure of the parts you have. the vented cobrs rotors are wider and you will need to make sure you have the right pads. the GT pads have more meat than the cobra pads.
rotors different thicknesses:
GT non vented rotors = thinner
cobra vented rotors = thicker
the pads are different thicknesses:
GT = .665" thickness
cobra = .585" thickness

sometimes parts counters dont pay to much attention to the things that really matter, so make sure of what you were given

You need a special brake tool that you can use to turn the pistons back in so you can put the new pads on. Turn to the right to turn them in. It does take some work. Make sure you pay attention to the direction and placement of the tits that line up to allow the installation. You will understand when you look for them. Usually close to straight up and down. The tool I have is a square multi-vehicle brake tool that looks like a die with different peg patterns for different types of brakes. You can get one at any parts store for less than $20.00, but you can't do back brakes without one.
