Hey guys, Im new to crown vics. I equitable got a 2000 P71 a couple months back and always since I got it the bracken pedal starts pulsating when I ‘m slowing down and turning at the lapp fourth dimension. chiefly when I ‘m pulling into parking spots and things like that. I was thinking it might be the ABS pump ? ? But I ‘m not veridical sure and I do n’t wan sodium precisely start throwing parts at it and wish for the best.

Any aid would be appreciated .

Yep, rotors. Does it shake very bad when slowing from gamey speed ? Know anything about when the last time the pads and rotors were replaced ?

I highly doubt its the rotors. It does n’t vibrate my steering wheel or any early sign of the zodiac of front rotors being bad. The bracken pedal actually feels like its pump and it lone does it when trying to pull in a parking blot or reversing out of one when Im turning the guidance wheel and brake at the same time .

No stimulate at high speeds. I run a service shop in AZ. The brakes and rotors are the 1st thing I checked when I pulled it on the rack. We do by and large imports there and none of my techs have any experience with this type emergence. I do n’t in truth want to delete the ABS, id quite fair fix the trouble.

Any serve would be appreciated. Thanks guys

one of your ABS senors is bent. It happened to my 2000 P73. It ‘s easy to test. find the fuse for the ABS and pull it out. if it stops then you know the trouble. the specify is to replace or bend back the detector.

Another possibility would be a crack up shade closed chain for the ABS sensors. If you have a scan tool that allows you to see your wheel speed PID ‘s, count at the roulette wheel speeds at all four corners and see if one looks a little twitchy compared to the rest. It will tell you which wheel to look at first base.

Good luck

I sold my snap on scanner frown ill have to take it to a friends shop to scan the ABS. I sold my snatch on scannerill have to take it to a friends denounce to scan the ABS .

I do n’t think heave rotors would cause the pedal to pulsate. Mine have been warped for a while and I have n’t experienced any pulsation in the pedal. Most probable the brakes are highly broken and need to be replaced.

These cars seem like they are ill-famed for heave rotors .

Think of it this way: Apply the brakes just enough to make the lads contact the rotors and start slowing down the car. If the rotors are warped, the warped section would be pushing back on the brake pads and calipers (causing the brake pedal to pulsate, since hydraulics are linear like that).

You may not get any pulsation at low speed. But, at high speed, the heat created by the braking from high speed will allow the rotors to warp enough to push back on the pads. think of it this means : Apply the brakes fair enough to make the lads contact the rotors and start slowing down the car.

buttocks rotors are warped. Rear rotor warpage causes brake pedal pulse, if the fronts are warped, you will feel steering wheel shaking over a pedal pulsation. Remember the rear rotora are solid besides, not vented like the fronts and consequently are easier to warp if they get a moment hot .
