My son has a 78 that the brake peddle is very sensitive at the top of the peddle throw. i have thought about shortening the peddle rod to make it a bit easier to manage, but there should ba a better sollution. Any ideas?
With power brakes?
Yes it has power brakes, in looking at the history from the reciepts this has been an on going problem. the booster has been replaced, brakes have been done several times, someone even had the rotors turn as part of thier trouble shooting. i have replaced all pads, rotors calipers and still the issue persists. i am wondering if the booster could be wrong?
I have a '79 that I've had the booster and master-cylinder off, so I should remember what it looks like, but I don't. I'm thinking there's an adjustment some where between the booster and the master. I can tell you on any system a travel-rod of sorts is used and giving more slop slows down the reaction time. I'd bet money your problem is adjustment at the brake pedal / booster / master-cylinder.
I read an interesting article some time back that was loaded with some good measurements and readings that are basic I suppose to all power brakes. I'm sure CCT has probably done something also however the one I recall is from Rod and Custom. The article is called "Braking It". It was in the April 2009 issue. If you put that in there search engine it will come up. I will also try to leave the link here for you. Hope it helps. Atleast you will know what to look for if you really wanted to dig in. It sounded like the vender was also helpful. Maybe your booster got changed out with something that doesn't match up. Good Luck!http://www.rodandcustommagazine.com/techarticles/0904rc_master_power_brakes_diagnostic_kit/index.html
Thanks i will look into it and hope for the best.
This sounds like an inlightening artical. i am going there now.
