cpmman Posted July 20, 2011 Share Posted July 20, 2011 How long should the power brake rod (the one that actuates the master cylinder) be in a 70 Monte Carlo? I do not have any play in the brake pedal with the car off. Brakes seem a bit tight when rolling as well. Quote Link to comment Share on other sites More sharing options...
ROMO Posted July 21, 2011 Share Posted July 21, 2011 I was just about to ask the same question. Quote Link to comment Share on other sites More sharing options...
cpmman Posted July 21, 2011 Author Share Posted July 21, 2011 No answers yet..but a seasoned mechanic just told me to trim the rod 1/8-1/4" at a time until there is anout 1/2" of play in the pedal with the car is turned off. Quote Link to comment Share on other sites More sharing options...
stangeba Posted July 22, 2011 Share Posted July 22, 2011 What has changed (or was repaired or replaced)? Did it always do this or did you replace the M/C or booster and now it acts this way? Do you have the old M/C to compair? I repaired a car one time where the cross shaft was so badly worn out the clutch and brake peddle were way out of whack. I believe you have a 4 speed with a clutch peddle so you may want to check the entire cross shaft bushing area before grinding away metal you may need.

cpmman Posted July 22, 2011 Author Share Posted July 22, 2011 Booster and M/C replaced..the rod with the new MC was to long so the brakes would not bleed. After some trimming of the rod, the brakes bled but now the front brakes are a bit tight and the pedal has no play. I presume a bit more timming will fix it but was wondering if there is a stock length. Clutch pedal is fine. Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted August 4, 2011 Share Posted August 4, 2011 Your are going to have to shorten the rod until there is at least 1/8 inch of free play, then readjust your brake light switch. Quote Link to comment Share on other sites More sharing options...
