Brakes?

I have had brake problems with my 1998 jeep cherokee,the brake pedal will almost touch the floor so I had it checked out and they told me it was the master cylinder.So I changed the master and the pedal is doing the same thing.This is a mail right hand drive jeep and I went to stop at a mail box and it just slid right past the box so thats when I notice the pedal almost touching the floor.If you guys can help me it would help me alot I need it have it ready by saturday.

Just to avoid assumptions, you have plenty of fluid in your resevoir and have bled the brakes?

Also, you do not have a line loose that is spraying fluid everywhere or possibly a wheel cylinder that is leaking? If it a wheel cylinder you'll see some white spots slung around on the inside of the tire where you have the trouble.

edit - abs by chance?

White spots???

Are the rear brakes adjusted properly (front ones too if drum)?

Emergency brake not working, or engaging at almost full travel is a good indicator of shoes out of adjustment.

This is the most common cause, due to automatic/self adjusters being froze up and not doing their job.

Is the ABS light on?

I just noticed you said 1998.......I guess you don't have drums on front anyway......

Do you even have them on back?

My Chevy had a leaking wheel cylinder. I was searching for the leak that was going on with my brakes and I noticed that particular tire had white looking stains where the fluid had dripped on it.

Wierd.......it wasn't a whitewall turned in and the fluid was making clean spots on the white was it?

I thought it might have been a typo for "wet" spots.

I am not much up on ABS, but understand that on some systems there is a specific way to bleed them. Also, did you bench bleed the M/C? If the pedal feels spongy when it goes that far down, it is likely air in the system. If it is hard, check the adjustment and condition of the pads/ shoes. The rod for the M/C may not be adjusted properly. Also may be a bad reman M/C.
