Had to at least see what the wheels looked like on it!
I’ve been messing with the brakes more on and off. Ended up taking the drum assemblies apart to double check that everything was okay. Shoes appear to fit perfect.
I did notice that the shoe material stuck out past the metal portion, so I ground that down in case it was causing the shoe to not sit flat on the backing plate.
Still not satisfied with the brake performance, I hypothesized that I needed a K30 master cylinder instead of the K20 unit, which gave me 1-5/16” bore instead of the 1-1/4” bore, meaning I would have a higher volume output, stiffer pedal feel, and less pedal travel, which is what I think this truck needs. So I picked up a K30 unit.
Painted!
Bench bled the unit
Just out of curiosity for comparison - it appears the K20 and K30 units are slightly different depths.
After all of this, I’m still not completely satisfied. I’ve also determined that the hydroboost unit doesn’t appear to be always working as it should, so I’ve ordered a new replacement. Unfortunately, it has an up to 90 day lead time.
