Re: Better Rear Brakes?
 
I was also told that switching the brake lines on the master from the factory setting is better (holds more pressure on the rear wheels) BUT I have never tried it and don't know anyone personally so this could be one of those old bench racing stories. Has anyone else tried this?
Thanks
Kevin

My 70 Nova held better on the starting line after we swapped the factory disc brakes for drums plus the drums were lighter. It's possible that there was a problem with the discs, but drums in the front worked better to stage. If I remember right, we picked up about 500 rpm over the discs.

In addition to re-arching the shoes and putting larger wheel cylinders, try to find a brake relining shop and ask them if they would put the same lining material used on forklift brakes. The coefficiency of friction of the forklift brake lining is higher.

Don't forget to check the rear drums for cracks every time you swap sides with the slicks, also its a good time to adjust the breaks. We could hold the cuda at 3200 rpm with 10 inch stock drums, of course changing the backing plates every year was required due to stretching the mounting holes.

X2, the front drum brakes will fix your problem.

Used to arc brake shoes many years ago. Essentially it matches the arc of the shoe to the arc of the drum. If you can't find anyplace to do it ( check for HD truck shops), good used shoes would be an option (they have worn to fit the drums). Also, your brake drums may have been turned too much, check them against std diameter.
