Grabbing Brake.

[David Stepney]

Here’s a silly problem for the cognoscenti. I have recently refined the front brakes on my RP and now find that, if I have left the car idle for a couple of days, the offside front brake grabs on initial application and does not release unless I reverse a foot or two. After a couple of applications, it behaves itself and doesn’t do it again until I have left the car for a day or two. It appears that the leading shoe (I.e. the rearmost one) is wrapping on. I have made sure that the shoes and cam mechanism is not sticking and tried swapping the drums over from side to side. All to no avail. I have done less that 400 miles since the redline, so is it a problem that might go away as the brakes bed in, or should I be looking for a more immediate problem?

On the road, the brakes are fine, pulling up square even on a emergency application.

Any thoughts?
