I just switched over to a set of 11" Front Brakes from fastbrakes into my 1999 Honda Civic SiR, and i think i need a new master cylinder. The shop i take my car to has a wrecked prelude sitting there with a fresh master cylinder, but my question is will it fit into my car, and even more importantly will it bolt up to my brake booster?

Thanks for your input

 

You dont want to mix-and-match brake system components, even if it does fit.

 

you have an 11/16ths now right? whats the point?

 

I thought the 2001 Prelude MC was a 1"

 

it probly wont work anyways, but 1" wont give u that much difference over 15/16ths

 

1" gives you almost 14% less fluid pressure vs. 15/16".

 

Less or more? I don't get how a 1" MC would give you less fluid pressure then 15/16"

fast brakes use stock calipers? if so you arent moving any more fluid volume. thus you shouldne need a bogger bore master cylinder.

Using the same vacuum booster? If so, you have the same force on the piston rod, larger piston area. If you use a different booster along with the bigger MC, then the size of the diaphragm in the booster has to be figured in there.

You want more braking force? Use a smaller MC and/or larger caliper pistons. The mechanical advantage of the hydraulic system is equal to the caliper piston area divided by the MC piston area.

THey use the ITR/Accord/Prelude Calipers
