My SUV shakes everytime I hit the brakes, what's wrong?

I have a Ford Escape SUV 4×4 and had its brakes changed by myself twice already. The problem persists, everytime I hit the brakes it shakes. What did I do wrong?

    You might not have done anything wrong. Have you checked the proportioning valve on the firewall? Have you bled the brakes after your brake work? have you drained and refilled the brake system?

    I’d try those, bleed it first, replace the fluid second, and check the proportioning valve last, before chalking it up to a bad brake job.

    Those valves can be weird.

    What year? does it have ABS? Pull the fuse for the ABS and try the stop again, see if the shudder goes away.

    When you said you replaced the brakes, did you check the rotors? If they are warped, out of round, or thin to the point where they are almost down to the fins, they will cause it as well.

    you can check for rotor warp by putting a dial indicator (cheap, Harbor Freight has one for about 10 bucks) on the inside or outside of the rotor, and turning it on the axle to see if there is runout. if there is, take it to a shop and see if they can turn them flat for you, or if they are too far gone and need replacement.

    Beyond that, the only thing left is a master cylinder, but you’d -probably- feel that pulse in your foot as well as in the car.

    It sounds like a warpped rotor or stuck caliper. Remove the front tires and spin the rotors. If you see any movement in and out replace the rotor.

    sounds like your front brake rotors need to be turned or replaced

    well if it shakes it prolly squels to pull the front tires off and on ure pads there will be a hook pin that sits near the rotor its and alarm type deal it tells u when ure pads are near time to change. pull the rotors down and hit the rotor with a high gritt paper and a good sander and sand the **** out of it to save some money or go and get new ones ure choice its the rotors. u should change the front brakes 2wice to every rear change

    Sounds like you need to replace your brake rotors. I had the same problem on a truck and I replace the rotors an it fixed the problem. Warped brake rotors on wet pavement could cause you brakes to lock up causing loss of control of the car. Trust me! I hit a school bus head on because of this problem.
