CMP brake question about both Ford & Chevy C30, C60, and C-GT and their Ford equivalents.
The issue is the, minor or upper adjustment, interval how many miles between adjustment are people getting? My C60S Radio body truck with the 261 engine, curb weight 12,000LBS, gets between 1000 & 2000 miles a year. My routine has been to adjust or check the adjustment each spring when do the general servicing. With the truck up on jack stands it is just makes the whole servicing easier.
Now normally over the years it has taken only the most minor adjustment of cams A & B (Fig. 6 - Adjusting Cams) maybe a few degrees. Once this is done the brake peddle is right back up at the top of the stroke.
The last three times I have done this three wheels RF, LF, LR all needed almost any nothing, but the Right Rear both A & B have needed much more. What I also noticed was that they turned much easier than all the others.
Has anybody else noticed a similar problem?
I had adjusted the brakes 3 months ago, recently I was not happy with the brake performance, peddle goes down about halfway and with a quick pump brings the peddle right back to the normal top point. So put the truck on jack stands and checked the adjustment and again the Right Rear was out of adjustment again.
