Well today I turned my rotors and everything was put on exactly how it was. But now whenever I push down on the brakes to stop my brake pedal raises up and down constantly as I press the brake pedal. I believe I just need to bleed te brakes but I wanted to see if anyone else has had this problem and see if I just need to bleed them or what you had to do?

 

bleed them first. if theres still an issue afterwards then look into it

 

ONE of the roters is not runing true it is warped or maby not seated on the spindle corectly perhaps there is some dirt or debris under it. bleeding will not cure a pulsating pedel

 

Since you truned your rotors and they are true, make sure thay are seated with out rust debris behind them. Your new/calipers need to be mounted securely and if there is space, instal shims between cyls and new linings for proper air gap/tollerences of pad to rotor. Test run out with a dial gauge to insure nothing is out of tolerence. Bad wheel brgs can lead to brake problems so make sure about them. You need to run your antilocks to get air completely out of system. Some don't like the mess if it not contained. I would recommend always replacing the worn rotor with new. There are some cool ones available.

 

Thanks and yea are some cool ones available but I def like the thought of turning them for free then the thought of forkin out 120+ for new rotors.

 

Well I bled them today and still the same problem.. I'm gonna drive it for the weekend an if it don't get better than Monday then I'm going to grind them again. If still not better than I will have to pay 110 for some new rotors. I'm pretty sure the rotors will be the problem considering everything was working fine until I turned them.

 

Not a terrible idea. I just figured bleeding them would be the free-ist way to possibly fix it. Wasn't so sure it would actually work after reading the rest of the posts. Good luck

 

It's a warped rotor. And by 'warped' I mean that it's not true anymore. And I'm only saying that because you said you bled them already.

 

Did you match up your replacement pads as to size and put them in properly. How many thousands of an inch did you cut off. Did you turn on the motor and abs pressure bleed? Navigate to Search box and read up on it.

 

Honestly I'm not so sure on how much I took off. I've personally never turned rotors so I got my buddy that I've seen do his and other peoples a thousand times. And I didn't get replacement pads bc the ones I have on are pretty much brand new. And no I didn't turn the motor on to bleed them. I've never done it this way bc I've only done it to 70's-80's model trucks before. How do I pressure bleed them? I'm doing all of this work in my shop at my school so I won't be working on it again until Monday. My truck still stops fine but just not very smoothly and my pedal pulsates.
