Brake caliper issues

I just did the 199mm tundra brake upgrade for my 97 limited (power stop) and the left wheel is still turning when I apply pressure to the brakes. I learned this when trying to torque my lugs. It may be worth mentioning that I replaced the brakes because the right side brake pads were completely worn it had warped the rotor while the left side pads were barely worn. many help would be appreciated.

 

When you were bleeding the system, were you getting any any brake fluid come out of the left front caliper's bleed nipple? And having bled the system, did the front left brake caliper pistons move when brakes were applied?

 

It bled fine fluid came out of the bleed nipple. Pistons did not move when I put pressure on the brakes.

 

This sounds like one of the brake circuits is not working. Assuming that the brake circuits are on a diagonal and if the front driver side caliper piston is not moving and we suspect it is the brake circuit, then the rear passenger side brake shoe pistons should not be moving either. Perhaps you can check the condition of the diagonal rear brake shoes to ascertain this. One cautionary note. If you do remove the rear brake drum, be careful in using the brake pedal as you could easily pop the brake shoe pistons out of their housing. On a side note, do you see any OBD codes?

 

No codes as of now. So I have to get into the rear brake drums to check if the piston is firing? Why couldn’t I just jack it up and see if it spins? I’m new to working in my car so sorry if anything a say sounds naive I’m just trying to learn.

 

You have it better as a first check. I was thinking that between the left and right rear brake shoes you should see a different wear rate
