914 rear brake conversion to 911 parts Options

[shoguneagle]

I have recently converted my 914 rear brakes to 911 ones. The changes were made from all the advice, threads, etc found on this site and 914club.com. I have been over the entire installation and everything seems in order and done correctly;

The problem relates to the left side rear e-brake shoes causing the rotor assembly not to rotate when everything is torqued down. The right side appears to rotate when torque is on the rotor. It appears the brake shoes are digging into the rotor when torque is applied. I do not notice any tracing of scaping anywhere on the inside of the rotor assembly. I am working on the idea that the clearance may be wrong such as brake shoes not arched properly, etc. These same shoes and rotors were used on the donating 911 so I am operating somewhat at a loss.

Any information and advice is greatly appreciated.

The idea that the backing plate could be bent or not installed properly to the swing axle after grindinng seems to be the most logical. I came to the samt conclusion the backing plate could be bent or not 90 degrees to the axle. I will check and see if it is true. I am thinking that the area requiring grounding of the ears was not completely ground down and I need to possibly address this issue.

I am also rechecking the stop welded in place inbetween the end of the two shoes.

Thanks for your input and assistance. Sorry about not providing pictures but I have been tied up inbetween the car and outside activities.

Give me a couple of days and I will get back to the thread with the cause of the problem and correction.

Thanks again,
