Hello,

This weekend I am going to see to the brakes of my silverado.
When the chevy brakes, she goes to the left. What could this be ?

 

The brakes on the left wheel are grabbing tighter than the right side. It could be the rotor, pads or the caliper.

 

How do I loosen the caliper ? I'v seen 2 imbus bolts. They are not europe standards. What's the standard ?

thx

 

I checked the piston. I opened the bleeder screw, and pushed the piston back, a little of brake fluid came out, then closed it again. So it's not the piston. The brake pads look good right and left, also the disks look good.
Is there something the proportions the left and right brake fluid ?

 

It's possible brake caliper slides are sticking. I'd try pulling the slides out and checking to see if they are dry or show signs of binding.
