What happens when you change the pads on an ABS Vehicle?
Concerns about changing the pads on an ABS-equipped vehicle include damage to the modulator valve assembly due to debris in the system, air trapped in the system due to improper bleeding and air being inadvertently introduced into the system when the pump motor pressurizes the accumulator after pad replacement.
Why does the brake pedal go down to the floor?
I have replaced rear brake pads and rotors on my 2010 highlander and right after I went to take the car for the test drive the brake pedal goes all the way to the floor. There is no leak anywhere. I scanned the car and it says ABS inlet valve coil Left circuit and gave me C1201 code and I was wondering if someone can help me with it.
How do you install a caliper on an ABS system?
Doing this will prevent any debris trapped in the caliper bore from being sent through the ABS system’s modulator valve assembly. Install the clips and shims from the old pads onto the new set, and install the new pads onto the bracket. Install the caliper over the pads, and bolt it securely to the caliper bracket.
Why does ABS light stay on after brake job?
Wheel bearing going – seems unlikely as it spun real easy, no noises, and light wasn’t on before brake job, came on immediately after brake job. 5. Wiring to ABS unit…where is ABS unit? I don’t think I went anywhere near that doing the rear brakes. Any other ideas come to mind? Why NO codes though?
How to replace rear brake pads on a Harley Davidson?
In this video, Bob and Mark show you how to replace rear brake pads on your Touring model if necessary. This Evo caliper is easy to work with. They teach you to be careful when applying lubrication to the caliper system that you only use a little bit of grease and anti-seize.

Why does the brake pedal go down after replacing the brake pads?
If they worked fine before the brake job, it would have to be something that happened during the procedure. ABS sensor seems unlikely to be the cause of your problem. Most likely air in the brake lines. I had the same problem after changing the brake pads. I used many days to figure out why. Actually, it is the caliper piston rubber seal worn out.
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.
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.
What happens when you have a false ABS activation?
False activation incidents involve the ABS modulator taking over braking or intervening to restore vehicle stability. The customer may feel feedback in the brake pedal like a pulsation or sudden drop. Some may also experience a drop in power or the vehicle may suddenly pull in one direction.
How does the ABS module affect the brake pads?
The ABS module or in some models the SBC Brake module will apply pressure to the brake pads at each of the individual wheels depending on the directions it receives from the vehicle’s control units. While it is less likely to fail, it is known to be a problem as well. Replacing the ABS Module can be costly.

What causes a car to activate its ABS system?
This problem usually starts with the wheel speed sensors. A weak signal from a sensor is interpreted as a locked wheel, which triggers the computer to activate the ABS system and release brake pressure in an attempt to unlock the wheel. The driver might experience a longer than normal stop.
