newby with a Jetfire & power brake question

[jensenracing77]

i just picked up a 62 Jetfire yesterday. it was registered here under Todd Houseman. i love the car and will post some pictures when i can. i was wondering about the Power brakes? they are not working but i have vacuum at the bellows under the dash. is this something i can rebuild or any recommendations?
thanks for your help.

if anyone else ever needs this info.. i found out that you can get the bellows style booster rebuilt with this guy. they are $155 to rebuild.

i am not convinced that i have a power booster problem. i have vacuum at the booster like i should and the check valve is working. i am wondering if there is a bracket that is to push on the yellow button (see picture) when you hit the brakes. does anyone have a picture of this area with power brakes that work?

i think i have answered my own question, i went out to look and see if there was a bracket or something like i mentioned above. well i think i figured it out. when i took it apart i think the button was not getting pushed by the little tab on the brake pedal. i am going to put it back together tomorrow night and see if i can make sure it is hooked up like i think it is supposed to be or if i can adjust something to let it push that button. i looked in the 63 assembly manual that wild about cars has posted but i can’t see good enough in the pictures.

i got the power system figured out and adjusted properly. it just takes a little looking and understanding the system. none of the power brake setup is covered in the CSM. while fixing this i found a real small drip of fluid on the back side of the master cylinder. i took it out to rebuild it but there is pitting in the bore. it is hard finding a power brake master cylinder for these cars. i found one at Kanter but it was a little pricey. i just hope it is the right thing when it gets here.

i got the cylinder today. the correct power brake master cylinder has a hole that is 1 11/16 deep in the back and has a 1 1/8 bore. i am not sure the details of the manual brake master cylinder but i found them several places. the only place that had this one was Kanter. i will get it on tomorrow and go for a test drive if the roads are good. i have only drove this car less than 1/4 mile so far.

With all drums, the car really doesn’t need power brakes. Dual circuit would
be nice. Front discs would make it a lot safer in wet weather; then you need
the brake booster. Bruce Roe
