wilwood master cylinder size?
 

I'm wanting to swap my power brakes (4 wheel disc) over to a manual set up with a wilwood master cylinder, (no booster) what size bore master do I need?.....7/8" or 1"?.....do I keep the stock distribution block on there?....I know I also need an adjustable proportioning valve for the rear disc...

Re: wilwood master cylinder size?
 

You only need the adjustable prop valve, not both. Typically you want a 7/8 for manual setup.

Re: wilwood master cylinder size?
 

have you done this swap?

Re: wilwood master cylinder size?
 

I always run a 1" bore on the wilwood master with manual brakes..

Re: wilwood master cylinder size?

It depends on the brake kits you have on which to run 1 and 7/8 are both usable.

Re: wilwood master cylinder size?
 

.....the rear is wildwood dynalite 4 piston 12" rotors, the front is stock disc, but going to be the 6 piston 14" rotors in the not too distant future....and yeah I need the prop valve, cause the rears will lock up in you get on them too hard....

Re: wilwood master cylinder size?
 

If your going to go with the 14 6 piston then go 7/8. I can get you the parts if you need them.

Does anyone know how well a wilwood master cylinder will work with factory brakes? front disk/rear drum

Re: wilwood master cylinder size?
 

I have not tried this. I think it can be done with a prop valve and residual valves in lines.

This master make install easier.

Does that come as a kit with the prop valve?

Re: wilwood master cylinder size?
 

It does come as a kit, I saw them on Jegs website. I'm sure one of the vendors on here can hook you up. I plan on using this kit when the time comes. Just have to figure out if I want to run manual brakes, power with a booster or hydroboost :lol:

picked it up today!

Re: wilwood master cylinder size?
 

will the brake pedal from a 67-72 fit in my 86? I ordered the lokar direct fit one, hopefully I can make it work..?

Re: wilwood master cylinder size?
 

done...

Re: wilwood master cylinder size?
 

the 1/4" brake line that runs to the rear brakes, should I change that to a 3/16" line??

Re: wilwood master cylinder size?
 

anybody?

Re: wilwood master cylinder size?
 

Looks good. What did you do about brake booster holes and bracket? I see shaved firewall, also how did the pedal work out?

Re: wilwood master cylinder size?
 

the bracket is part of the booster....I cut all the studs off, removed them, and welded up the two lower holes then bolted the m/c up with new stainless bolts. the pedals are on back order.... :(

Re: wilwood master cylinder size?
 

I would leave the 1/4" line as is. Prop valve will control pressure.

Re: wilwood master cylinder size?
 

too late. lol. I changed the rear line to 3/16", and ran new front lines, got a wildwood adjustable prop valve too....front pads are done, and the bleeders are seized so I bought the wildwood d52's for the front. also got my old line lock hooked up as well.

Re: wilwood master cylinder size?
 

I don't mean to hack thread but the question was asked about which size bore m/c to use if using manual m/c with disc front and drum rear? I am going to make this change soon myself just to clean up engine bay.

Re: wilwood master cylinder size?
 

Anyone has the answer to this question? Im also interested in doing this to replace the big brake booster setup on my 72.

Re: wilwood master cylinder size?
 

with front disc and the rear drum brakes I would be guessing at 1 1/8" bore mc...but you might want to call wildwood to be 100%.
