We got the brake shaft/rod from a '65 C10 with a stock brake booster. The rod was adjustable so we adjusted it out with about a 1/4 inch left of threads so we didnt want to adjust it out any further. We had to pull the brake pedal close to the floor to be able to put the bolt throught the pedal. The brake pedal is now close to the same hight at the gas pedal maybe slightly higher. I need a longer rod! (Haha i wonder how many guys say that). I need a longer rod but have no clue as to where to get one if the one from a '65 that had a stock brake booster is to short. The booster is mounted the exact same way. If anyone knows what kind of vehicle to get this rod from or where to buy one please let me know. Also the last problem is on the stock system there is a Y connector that splits engine vacuum from the PCV valve and the booster. I went to napa and all the ad was a T connector for the cooling system. Does anyone know if this Y connecter is of much importance or will a T work? If anyone has an answer to either of these questions it would be much appreciated.
Thanks

I think the ones I remember working with were 5/16", standard thread. The vacuum tee can be shaped any way you like, as long as it will flow vacuum. I like to use a 30-lb. Freon canister mounted under the cab somewhere as a vacuum reservoir, to allow more than one brake application before running out of vacuum if the engine stalls.

Make sure your all-thread is going to be strong enough for the application of the brakes in a panic stop, and you should be good.

Likewise for fasteners on this installation use grade 8 nuts and washers. Don't scrimp on these fasteners and you will not hesitate to mash the pedal knowing nothing will bend or break. | | |
