Brakes sticking

Deleon · Nov 22, 2024

hello just joined i have a 2004 yukon denali about a month ago it started to have a problem with the front brakes sticking mainly the drivers side I replaced the caliper, brake pads,and brake hoses and its only gotten worse

No abs lights on
I am getting a sercive stability message dont know if that correlates

If anyone could give me any suggestions on what to do it would be greatly appreciated as this is becoming very frustrating thanks.

being you already threw the parts cannon at it, get it scanned for them abs codes.

Pics of the truck, please.

Do you have access to a quality bi-directional scanner? It would be good to determine if there are any underlying error codes that could help identify the source of your issue. You could also use the scanner to run the ABS air purge process, to ensure that the ABS is not related to your issue.

Got it scanned got the code c0131 my mechanic thinks its either the master cylinder Or the brake pressure modulator valve would either of those be the fix?

Wouldnt be the master cylinder. When the master cylinder fails it doesnt apply any pressure to the calipers. Could be the ABS manifold (Modulator valve body). You arent getting any other codes at all? If a wheel speed sensor is failing then that would turn off your stabil trak and create the message you are seeing.

if the brake lights work then it's either abs module or control valve, per the code.....C0131

you might want to just let a shop diag and repair it. https://www.google.com/search?q=c0131&sourceid=chrome&ie=UTF-8 could be simple or hard. testing needs to be done to narrow it down.
