thanksPedal ratio is only different between power and manual brakes. I've never had to change pedal ratio when converting to disc brakes
Ok. Ive got manual 4 wheel discs so guess I'm stuck with hard pedal effort. Think my cam is too radical for a booster set up. How much vacuum is required?
Yup, that will multiply your effort thus making it brake more efficiently.Run a 7/8" master cylinder. 4 wheels discs with manual will feel like power brakes.
I`ve got a 87 dodge diplomat master cyl on mine, it`s a little more effort than I`d like. what mopar master cyl would be better for 4 wheel discs ?Run a 7/8" master cylinder. 4 wheels discs with manual will feel like power brakes.
The ratio is changed through the bellcrank assembly that is sandwiched between the booster mounting brackets.
Manual discs use the same setup as drum, but take a ton of pedal effort to get the job done.
I'll try that. I am currently using a 1 1/32 .
I think the 87diplomat master cyl is a small bore.Order a 73-75 A-body POWER brake 7/8" bore MC but run it manually. I guarantee you will like it. Less effort than a 1-3/32.
I have tried 1-1/8, 1-32 and 7/8 in my 68 cuda with manual 73-75 discs. The 7/8 bore is the way to go for most people.
If you go with the manual 4 wheel discs, do you need a prop valve in the system at all if starting with manual drum at all wheels?Run a 7/8" master cylinder. 4 wheels discs with manual will feel like power brakes.
why? w/ the stock one, all wheels get the same just like before. -------?If you go with the manual 4 wheel discs, do you need a prop valve in the system at all if starting with manual drum at all wheels?
