Greenbrier parking brake problem
Posted by: thumper477 ()

I have owned dozens of corvairs since 1970 and the thing that always impressed me was how good the parking brakes work on these cars.My 64 greenbrier is the exception to this.I have to pull my brains out to get the parking brake to hold on even the slightest incline.Every thing seems to check out ok but obviously I am missing something.Any suggestions?

Cables stretched?
They are all done correctly, but just do not have enough pull?
Are your rear brakes adjusted correctly? Is your parking brake using up all opf its pull just trying to close a large gap?
I don't know, just throwing out some ideas.

Suggest going underneath and tighten the cable up a bit back where it splits. Mine has a sweet spot that works and either side of that, it is either too loose or so tight its one click and thats all the travel.

Also, I assume you are pressing the foot pedal firmly as you engage the hand brake. Mine wont engage properly if I dont do that.

Thumper, This may not be your situation but I've seen cases where the cables and adjustment were fine but even during normal stopping the brakes didn't work well because of poor shoe to drum contact. So of course the shoes aren't likely to grip good for the park brake either.

That brings up the question...

Are your rear wheels cambered? They need to be vertical + or - 1 degree.

New FCs had way more positive camber than that and the brakes worked fine.

Is the undercar "amplification" lever in place and working correctly?
