I have just put aerospace rear drag brakes on the rear. Four piston 1.75 caliper. The car has Wilwood front drag brakes four piston 1.75 calipers. Do I need to change to a 1-1/8" bore master cylinder? And do I need a proportional valve and a 2 psi residential valve? Or will it work with the stock setup. The car is a 90 fox coupe.

I put a Skinny Kids Big Block kit. Call Mark @ Racecraft he can tell you what would work perfect.

 

[Max rider]

Ok will do. Just looking to get it right the first time.

Use the 1-1/8 bore, no prop or residuals. we use that with duel rear cals even mounted floor level and no problems. just get it bled right.

Yea I sure hope it's that easy. Can I get this M\C from the local parts house? Or do I have to order one?

 

[MisturG]

Call SkinnyKid.

i've got aerospace f/r disk on my coupe and using a Dorman m/c off a chrysler. had to grind the ball on my rod down to fit into the m/c, but works like a dream.
using it with a manual prop valve inline at the union on the pass side firewall brake line

 

[Max rider]

We use a 83 ranger master for man brakes,its alum,and the piston is large.lines come out toward drivers side,works perfect

 

[fatboyee]

yeah. just gotta get to work and look up the old invoice.
you'll need to lose the stock prop valve (brass piece on driver strut tower). i'm not using a residual valve - everything i read said if the reservoir is mounted below the calipers it's needed. but not in my case. car's stopped repeatedly from 150 @ 3300lb with no problems, stops fine on the street also

 

[Max rider]

Yea so you think I will need a prop valve. Some say yea and some say no. I think I will get one just in case.

 

[fatboyee]

dunno if i "need" it, but i have it adjusted to where the car stops like a brick. don't nose dive, just phucking stops lol

I useda aluminum master cylinder bought new that goes on 85-86 SVO mustang ,worked well. I took it of yrslater and went with one that had left hand fittings.

have the SVO for sale if interested

 

[Fordjunky]

When I added the rears brakes I used the 84-86 SVO 1-1/8 master cylinder also on the stock booster of my 89 stang. I removed the stock proportion valve & added the adjustable on the rear line. Works real well.

Mark at RaceCraft..............thats what we have

I gutted the stock prop. valve and installed a plug kit from Ford Racing. I used a proportioning valve from Wilwood. (I like to take some front brake out for finish line safety, etc.)

I relocated the rod from the MC to one inch lower on the pedal. Much better ratio for pedal effort.

Fox body....Strange front and rear.

My MC came from Skinny Kid.....maybe 6 years ago.

 

[Colt]

I gutted my prop. valve, welded the hole in the cap.. Used a Ford racing prop valve. I'm just using a stock style 1 1/8th's bore MC ( alum body, plastic fluid res. ).. I run Aerospace brakes up front, the rears are stockers off a 04 Cobra.. If your not wearing the harness it will put ya through the windshield.
