Firewall Power Brake Unit for 33 HR

[GlennC]

I'm doing some revisions to my car. The brakes are one area I'm addressing. I would like to go with power brakes but still use the Wilwood pedal box that came with the kit. I've done a little research on the subject and it seems that the Whitby unit is the only one available. Anybody have another option? How has the Whitby unit been working? Anybody else done a conversion?

Thanks

Yes the Whitby unit will work. You may have your patience tried waiting for it. Ask me how I know. LOL. But worth the wait IMO. You can see it in my 35 thread.

I switched my master cylinders to the firewall so I could use power brakes if needed. See pic.92683
This just took one pedal change and a belcrank to reverse the push of the brake pedal and move it up to clear my valve cover.

Glenn,

What brakes do you have now? Stock mustang on rear, Wilwood on front, stock mustang all around?

Nice! You have a P/N for that M/C? And if you decide to go power, are you going to use the Whitbey booster, or which booster? I like how your M/C is flat whereas the Whitbey unit is angled up from the firewall.

On the subject of brakes for 33'.. REAR brakes. Mustang 8.8 rear caliper is on Back side of axle. I Heard,,,, that it should be flipped to front side for Park Brake concerns..... Is this SO???? Would rather just leave it where it is.

Hi

I have wilwood 13” rotors with 6 piston calipers front and 12.5” rear rotors with 4 piston calipers. I started with a 1” bore Wildwood master cylinder but I didn’t like the pedal feel so I went to a 7/8” Wilwood master. I feel no need for power brakes at this time, but I did mock up with a 9” dual vacuum booster to see if it would fit and it did. Because of the cam I am running in my motor, I have no manifold vacuum at idle so I would have to go Hydroboost unit and that is a hole new can of worms.

What was nice about this setup is you can put your gauges right behind the steering wheel where they belong. I used the large gauges not supplied, 5” tach and speedo. There was about an inch clearance between the gauges and steering column holder when I mount the body

I am not sure what brakes you have now or if this would work for you.

I kept mine on the rear. I have found no reason, so far, to move them.92761

TomH33, do you have pic's of your peddle assembly with the bell crank? I too want to move my master cylinder to the firewall.
