I ended up getting one for the junk yard, Its looks like a stock one that came with the car. I figured id get one from there first to make sure it was the master. It works so im just going to use it till it does again (if it does).

Hi again

Having anther problem with my brakes now, I put the used master in and bled the system and all was fine untill yesterday. It felt like the drivers side caliper was sticking and then let go after a few mins. But on emy way home from work it felt like it froze and the pads were dragging on the rotor and when i came to a light the they were smoking from that caliper and i was almost home so i just kept going and right before i got home the brake pedal got really soft again. I figure it just over heated or something so i parked it for the night. Today on my way to work pedel is hard but slowly gets softer but the werid part is if i hard it hard then the drivers tire will lock up and not the passenger (fronts). Could i need a new caliper or could i have gotten a bad master cylinder? Please help :helpsmilie:

You almost need a new thread on this, it's getting a little confusing (you are talking about the fronts now, right?).

But.......

It sounds to me like you need a new front caliper for the driver's side that's locking up.

If you've never replaced this caliper, plus you put new rotors and pads on the front, you've probably pushed that cylinder piston way back into a corroded sticky area of the old caliper cylinder. I had this terrible problem on my old Jeep XJ and a new caliper did the job.

The fact that the problem is only on one side increases the probability of a bad caliper rather than the master cylinder (but you never know).

If you replace the one front caliper, replace the other front caliper as well. Always do things like this in "twos".

Be sure to get quality new or remanufactured calipers from a place you trust.

Luck!
