Thanks Ken. I've read of potential issues with the rear brakes. Assembly of the brake hardware was checked by at least 2 different shops and confirmed as ok but I'll have another look. While doing the recent trailing arm R&R, I noted on one side that shoe wear was even, the adjuster clicked, adjusters turn fine. BUT.... it's possible I could improve the relationship of the e-brake cable and shoe adjustment as per Dennis Haynes comments. Pedal height is fine, the vehicle will stop but if I push pedal hard enough, it will bottom out and pedal does not feel as good as that on my '88 meh. ;) On Mon, May 18, 2015 at 8:08 AM, kenneth wilford (Van-Again) < kenwilfy@comcast.net> wrote: > Neil, I have done many, many full brake system refurbishments over the > years.
