What causes your brake pads to move back and forth?
Warped brake rotors will cause the brake pads to move back and forth over the uneven brake rotor surface, this movement can then be felt through the brake pedal and is an indication that your brake rotors need to be replaced. How Long Should Brake Rotors Last? Brake rotors like brake pads will wear down based on how the car is driven.
Why does the ABS light go off when you replace the brake?
When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. In your case these sensors may have been bumped or need to be reset due to the movement when the brakes were replaced.
How does ABS and traction control system work?
Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car’s ECU.
What causes a brake caliper to get sticky?
The job of a brake caliper is to squeeze the brake pads against your brake rotors, which slows your vehicle down. It’s the motion of the piston inside the caliper unit that causes this contact. Due to wear from heat or road debris, the piston can get sticky.
How to prevent damage to ABS modulators During brake pads?
Then, while depressing the caliper piston, open the bleed screw to allow the brake fluid to escape. Your second option is to not open the bleed screw and don’t block the brake hose. This must be done carefully, but if you take at least 60 seconds to slowly depress the caliper piston then you normally will not stir up any sludge or debris.
When does the ABS brake light come on?
If any of the teeth are damaged or missing, the ABS brake light will come on, warning the driver of a problem. The new style ABS systems use a magnetic encoder built into the wheel bearing, and if the wheel bearing is installed backward with the encoder facing out, it won’t take long before your ABS light is on and your stress level goes up.
How to replace rear brake pads and rotors?
Step 5 – Using a pair of dikes remove the rotor retainer clip which is used in initial assembly and will not be reinstalled. Step 6 – Next, use a socket to remove both upper and lower caliper mounting bolts. Use a wrench if necessary to secure the slide.
