[Bricklin] Brake Question

[Mike Walsh]

Friends,

I replaced the brake booster and master cylinder with a rebuilt Hornet 
unit, however, the hole for the bolt that engages the brake booster 
seems to be "wallowed" out and moves quite a bit before engaging the 
booster. The result is that I have to push on the pedal several inches 
before the brakes engage (which is quite disconcerting).

Is there a bushing of some type that keeps the bolt from moving?

Thanks,

Mike
