Symptoms
Pulling, a low or spongy pedal, seized adjusters or wheel cylinders on a truck that has been parked.
The fix, step by step
- Strip each drum, clean and inspect the shoes and drums, and replace wheel cylinders and hardware.
- SNLC found seized rear adjuster pistons and trashed rear backing plates on his 1964, and none of four master cylinders were usable until one was bored and sleeved in stainless.
- Fit new flexible hoses, bleed the system and adjust the shoes.
- Many owners have added vacuum assist; check that any conversion was done properly.
