Brake Shoe Adjuster??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is the adjuster on for the brake shoes for a 70 C20 an automatic adjuster? Latly I have noticed that my brake pedal bottoms out every once in a while. I have blead the brakes and there is no air in system. Do I just need to adjust the adjuster or do I need to put new brake shoes in? Thanks

It doesn't hurt to jack the truck up, pull the wheels and have a looksee every now and then. If you haven't done that for a long time then you might have some surprizes. If there is no meat left on the shoes or if the shoes are worn unevenly to the extreme then its time for new ones. Check your drums as well for uneven wear. The ratchet pawl (little toothed wheel) at the bottom of the brake assembly is the manual/auto adjustment. Backing up and slamming on the brakes should set the brakes. Sometimes the auto-adjust feature doesn't work well and lubricating the ratchet assembly with Never-Seize (graphite) helps. I usually do it manually by tightening the little wheel until I get only one revolution out of the big wheel,

.

I just did my front brakes today (discs). The wear indicators were making noise the last few days so I figured I better do something before my rotors got scored. Baby's got a new pair of shoes and the rotors don't need turning. Preventative medicine. Too many people don't pay attention and later end up paying big money.
