brake noise
 

I have a 95 blazer and I just replaced the CV axles, upper and lower ball joints, brake calipers and pads and the sway bar bushings. I bled the brakes and everything seemed fine but then it started making a groaning noise which seems to be coming from the left front wheel. When I tap the brake peddle it stops but then comes right back when i let the peddle up. I looked in the book and it says that I need to depress a pin on the combination valve when I bleed the ABS. I can not find the combination valve nor the pin that needs depressing. Can someone please HELP! This noise is driving me nuts.

i dont think you have a proportioning vavle with that pin, i believe that valve is integrated into the abs unit

what always seemed to work for me on the older trucks if the brake light stayed on or it felt like the pin was push i would just stomp the brakes really hard that would usually click it back on. but if you think the noise is coming from the front tire its possible something could just be rubbing
