When applying extra pressure to the brake pedal the Impala will veer hard right. By applying normal pressure the car will stop with a slight pull. It would seem the drivers side front brakes is not working properly and the passenger side is doing most of the work.
The rubber hose was visibly intact but no telling how it functioned with brake fluid and pressure applied. I’ll be replacing the hose as a maintenance precaution. I need to research the hose length. It turns out there are two different sizes but not by much. I went and ordered the longer part. It’s approximately 8mm longer. I’d rather have to much hose then not enough.
The driver side brake cylinder was completely seized and rusted out. The official service manual specifies a piston to cylinder gap between 0.003 to 0.006. This part was so crusted with rust you couldn’t slide any gauge in between. I ordered a new part, there is a left and right replacement part.
I may have to replace the passenger side brake cylinder if I’m unable to crack open the bleeder valve. My first attempt on the passenger side to see if it would break free was unsuccessful.
