BRAKE MASTER CYLINDER

[walt reynolds]

I am really tired of adjusting valves with the power brake unit in the way. I want to remove the booster and install a properly sized master cylinder. My car has original 4 piston calipers in front and drum brakes in the rear. Anyone have an idea what size master cylinder I should use?

On the Mustang forum I hang out on for vintage Mustangs, 15/16" to 1" piston seems to work well for a manual master cylinder on disc/drum. I guess it's a good starting point You could also or maybe have to change the pedal ratio to.

I had a 67 Camaro with the 4 piston fronts/drum rear.... used a 1 1/8" master cylinder... .worked okay, however, the 4 piston calipers were never all they were supposed to be - in the end, I swapped to later Camaro single cylinder and stored (then sold) the originals when I sold the car.

MP shows a 1'' bore on dsc/drum setup , doesnt specify 4 piston or not.

Re: BRAKE MASTER CYLINDER

If going to manual brakes you'll need a master cylinder with a "smaller" bore than the ones used with Power Brakes. The smaller bore actually creates more pressure. Saying that I put a Wilwood Tandem master cylinder with a 7/8" bore on my '71 camaro that has manual brakes and four piston Wilwood calipers on all 4 corners. I actually called Wilwood and asked them which one to run. Here's a link to the one at summit.

You might also want to look into one of these, it might also make it so you can keep your power brake setup.

I thought a Corvette came with Manual brakes and 4 piston calipers.

there should be a hole or you drill one for the change in leverage needed

If your running manual brakes that bore is to big, you'd be better off going to a 1" or 7/8" bore like I have.

How well does your stop at any speed ???

It will also depend on your leverage point

Now take your leverage point and add the small diameter bore master cylinder and it'll act just like power brakes. ;)

It's all about fluid compression. ;)

fluid doesn't compress,, thats why it's used..
if it does compress it's got air in the lines(system)
