jerking brake problem
 

i had cts-v brakes on my car took them off and sold them bought new calipers and rotors after the installation the car did fine with brakes. i order a set of welds and mounted them since them being mounted both front wheel sensors are throwing codes and the car jerks to the right when the brake pedal is pressed. i tried re-bleeding the brakes for the jerking but i dont understand why my wheel sensors are throwing codes after mounting welds. anyone else have any problems like this?

are they different sized wheels? (front vs rear) ive heard of the abs not liking that sometimes... or check torque specs of lug nuts? uneven tire wear? are the brake components all new or is a caliper sticking? pads uneven? etc...

+1. If the wheels are a smaller size than the ABS computer is expecting, the speed of rotation will not match the car speed and the computer will think the wheels are slipping.

If you don't have a caliper hanging up, a bad hub/wheel bearing can trigger the brake jerking you describe via the ABS sensor, I've seen this symptom on a bunch of GM trucks.

The posts about tire size are something to consider also.

well i didnt have a problem, until i put rear welds on it with dr's as soon as i mounted them it threw the codes shit went haywire i order front runners and have my welds on every day i checked out all my speed sensor wires i replaced on it had be rubbed in two but still threw codes for speed sensors

How are your front wheel bearings, any play or noise?

mikey67 i have no play in front bearings

What are the codes you are getting and what are you tire sizes?

More than likely you have different size diameter tires which is causing the problem.
