When I brake the car surges. Feels like disks are warped but has recently had new brakes. This started surging about 8 months after the brakes were replaced. Could it be the fuel pressure regulator??

If the vehicle only surges when braking sounds like you have a brake pulsation. If the brakes have become overheated like when driving down a mountain this can warp the brake rotors. They will need to be machined or replaced.

FEELS LIKE THE REAR END IS BOUNCING WHEN BRAKING THRU 25 TO 20 MPH. DO NOT FEEL ANY THING IN BRAKE PEDAL. FINE WHEN NO BRAKES ARE APPLIED.


usually if you cant feel a brake pulsation in the peddel or steering, its the rear brakes that may be out of true (warped) if disk. Also bad shocks will no longer dampen braking in rear.

I recently put new front brake pads and had rotors turned on the front end of my 2003 tundra sr5,after a month of driving i'm getting the pulsation when braking back which is why i made this repai


HI if you have pulsation after a month you must replace the rotors
they are too thin and the heat is warping them faster then before you
had them turned
note you replace brake pads and rotors

good luck

We change the front roter and now the brake pettle pumps when i brake


Pumps when you Brake? Do you mean you have to pump it to get it to brake or it surges the brake pedal? When the rotor was changed, most likely you had to compress the Caliper to get it on and may have changed the pads while you were there. If that is the case then sometimes the seals in the Caliper will roll instead of sliding back properly. If this is the case and you have to pump the brakes because they are spongey then you will need to replace the caliper. If the brake pedal is surging when you apply the brake (which would also be felt in the steering wheel then the new rotor was either incorrectly installed or is warped.

If you feel a pulsing in the brake pedal when you apply the brakes, your brake rotors are warped. Replace them or have them cut true again.

2003 Ford Taurus vibrates when I brake but not all the time. Sometimes it shudders very violently when coming to a stop. The steering wheel and it feels like the entire car does this. There is no squeeling...


Need to replace the disc brake rotors, they are warped.
On these disc brakes systems, the wheel lugs have to be torqued down when the wheel is put back on, or the rotors will warp after awhile.

Brakes


It sounds like the rotor (brake disk) is warped. That would cause the pads to wear much more quickly because the disk "wobbles".
The warped disk can also cause the noise, depending on how bad the warp is.
When most shops change pads, they usually recommend that you "turn" the rotors, it is a way of truing the disk.
