Hi folks,
We're in the middle of what has become a ground-up restoration of our '67 7ECA. Having just refurbished the brakes and reinstalling, I've come across a bit of a question regarding the parking brake lever on the Cleveland master cylinders (P/N 10-5)..
These devices have a lever toward the rear of the master cylinder that engages the parking brake, by apparently blocking the return flow of brake fluid once you have pressed the pedals and engaged the hand lever. On the left master cylinder, the lever on that cylinder seems to have a "stop" that keeps the retracting spring from pulling it "too far" to disengage the parking brake, making the lever stop at, oh, about a 45 degree angle relative to the cylinder itself. On the right brake, however, that lever travels farther than that, thus the retracting spring pulls it as far aft as it can until the spring is actually a bit slack and lying against a frame tubing member, pulling the lever back, oh, say about to 60 degrees vs. the 45 for the left side (measurements very approximate, just to give you a picture).
What I'm wondering is a) is the stop on the left actually a defect in the brake or intentional; b) thus, is the lack of a stop on the right side something that is missing; c) does it matter how far back the retracting spring pulls the parking brake lever on the master cylinder; or d) is the final position of that lever when retracted simply governed by the position the cables from the parking brake *handle* rests at?
Anyone know?
Thanks!
