Re: Brake Fade? What Brake Fade?

Also...when doing a brake shoe replacement, the Service Manual discusses the ominous "Nibs".

I thought this was a bit of overkill however it does make a big difference in the brake shoe alignment to adjust the nibs correctly.

I still dont know what a "Nib" is I do know that this procedure centers the brake shoes in the drum correctly.

Essentially the anchor pin (top pin that the brake shoes are spring loaded to butt into) is not round shaped but it is actually a cam.

When the "Brake Adjustment Major" procedure is followed, it instructs you to tighten the star adjuster until the wheel is "just locked" (I read barely possible to turn by hand) and then loosen the adjustment 6 clicks and now the wheel will spin with just a bit of brake drag.

Then the SM tells you to loosen the anchor pin lock nut and then rotate the anchor pin until the wheel spins freely and then tighten the locking pin (making sure you do not accidentally turn the anchor pin).

Then adjust as Ross recommended.

This made a big deal of difference on my dads car. Prior to this it seemed that I had to loosen the star adjuster way more than the 16 clicks to keep a shoe from sliding on the drum.

Also ensure your primary and secondary shoes are installed correctly so that they "self energize" correctly. I guess I don't know why they don't simply install two shoes with the longer liner so that both are the "secondary" shoe?!?!?
