What to do if your brake pedal is pulsing?
To disable ABS, remove the fuse for it in the fuse box that is under the hood. Do have a shop look at your ABS system if the light has been coming on. Erratic brakes are not something you would want.
Why are the brakes on my GM Truck pulsating?
Any help would be greatly appreciated. The ABS – Anti-lock brakes will do this. This problem can be caused by the wrong size tires. Basically the ABS system needs to “know” the size of the tires you have installed. This would be a GM dealer service thing.
Is there a problem with my Silverado ABS?
Sorry…
Why does my abs go bad under 5 mph?
A dealer has AT LEAST a tech2 scanner which has graphing capabilities. Its easy, you graph the data of all 4 wheels (3 with a solid axle), stop the car and the wheel the loses signal is the culprit. Usually under 5 mph the bad will read 0 mph indicating a lock wheel to activate abs.

What causes a soft brake pedal on a Chevy?
Soft or Spongy Brake Pedal: Too much air in the system due to improper bleeding is usually the cause of this problem. However, it can also be due to fluid loss or a low fluid level. Bleed the brake lines as recommended by Chevy to fix this. You could also have a ballooning brake hose when the brakes are applied.
What does it mean when your brake pedal is sinking?
Sinking Pedal: You may notice this while sitting at a stop light. A slow descent of the brake pedal means that the pressure is leaking out of the master cylinder. The brakes can fail if your hydraulic system or master cylinder is leaking. Pulsation: This is the symptom of a brake rotor that has warped.

What causes brakes to pulsate right after rotor and pad?
Your problem can only be because of: Wrong or defective parts, incorrect fitting damage such as not using a caliper piston retraction tool, incorrect re-assembly of shims and bolts and anti-rattle springs, previous damage or mis-alignment being masked by the old pad wear, a foreign body introduced into the system.
What causes a pedal to pulsate on a mower?
What can occur is that a small amount of rust will form on the hub flange. If the rust is not removed or the new rotor is mounted on the rust spot (the extra hole in the new rotor is not exposing the rust spot) the rotor will not sit flat on the hub. When the lug nuts are tightened the rotor will twist, resulting in pedal pulsation.
Why do my brakes shimmy when I run through a puddle?
What is passed off as a “warped rotor”, and blamed on the user running through a puddle after heating the brakes, is a myth. The shimmy feeling that comes from brakes is usually due to uneven friction material build-up on the rotor.
Can a warped brake rotor cause pedal pulsation?
The term “warped brake rotor” is used pretty loosely to define any brake rotor that isn’t flat and parallel with the plane of rotation. But there are other things that can cause brake pedal pulsation and there are ways that rotors can distort that don’t always produce pedal pulsation, but do affect braking.
Is the pulsing brake pedal necessarily an ABS issue?
Then the ABS light turns on and brakes work normally for the rest of the time. It is not easy to reproduce this issue. On average it happens once every two days. Is the pulsing brake pedal necessarily an ABS issue?
What causes pedal pulsation on a race car?
He said that, whether on a race car or a street-driven grocery getter, the rotor irregularity that most commonly causes pedal pulsation results from uneven transfer of friction material from the pad to the rotor. To understand this, we need to understand two basic concepts about brakes.
Why do my brakes pulsate when I brake hard?
ABS’s automatically pulsate the brakes for you while braking hard to prevent them from locking up and causing the vehicle to slide into whatever you’re trying to avoid. Unfortunately, one of the most common causes of vibrating, pulsating or grinding brakes is also the reason they sometimes seem…
