Hello everyone. After a long hard winter my old truck is ready to roll and get tuned up. I noticed when I was driving late Friday night when the brakes were applied firmly the truck drifted to the right and I had to correct it by turning the steering wheel left to keep straight. I am not sure what the cause might be. I put the truck up on my lift and all looks good, no leaks and the fluid is clean. Any advice would be great and thanks in advance for your help.
