scarebird conversion started!
Hey everyone. I got started on my scarebird conversion today. Here are some pics. I do have a few questions though. I want to put a factory GM style proportioning valve on mine. How do I route the lines into and out of the valve? I also noticed I need some sway bar bushings. Are these made? Can I get a generic replacement?

2 things to check when you take the hubs in to the machine shop. 1. You need to turne down the outside of the hub to fit inside the new disks. 2. You may need to turn the face of the hub there the studs are. Some of them have a slight taper that will not allow the disk to turn true. Level the face of the hub and that wobble is gone.

Looks like you are missing the metal "backer" inside U shaped clamp. I might have a photo of what it looks like all together.

missing part?
Quote:
As to the rubber bushing part, I doubt there is a specific "Tempest" part available at the parts stores but I believe that with a little bit of sorting through some pieces they have for other cars you could find sustitutes, probably even in polyurethane. I seem to recall the stabilizer bar is 11/16" in diameter. Notice the bracket has "grooves" in it with the U-shaped piece having similar patterns that fit into the bracket. These grooves probably serve a dual purpose of holding the stuff in line and "cinching down" the rubber. |

Sway Bar Bushings
I am thinking 62 and 63 sway bars are the same as far as that rubber bushing goes.

Thanks for the pics and info everyone. Anyone installed a proportioning valve on their car?

Thanks for the picture. I have another question. I just finished opening up the holes for the fairmount master cylinder. However, my master cylinder doesn't have a push rod on the back of it? Do you simply swap the one out of the factory tempest master cylinder and lengthen it so that the proper stroke length is achieved? Thanks.

MC
Sounds like you have a master cylinder for a "power brake" set up. My Fairmont MC had a rod attached and was for a non power application.

Fairmont Master Cyl on a 62-63 Tempest
I used a non power MC as well. If the boosted Fairmont MC does not have a very deep (we are talking at least 2 or 2 1/2") "pocket" in the push rod area I would not use it. If the push rod ever slipped out you would be in terrible trouble. The non power Fairmont MC I ended up getting had a pre-attached push rod (as I recall) that ended in a loop. I sawed off the loop, turned down the rod into 3/8"X24 threads and attached my junction. First 2 photos below are my mock-up of that prior to putting it back underneath the dash. Keep in mind that my car(s) are '63s so a '62 may have some minor differences in the firewall form or shape.
Hopefully what worked on my '63 would most likely work on your '62 with some minor tweaks here and there.

Nice pictures Peter. I did the same thing with a Fairmont MC. I wish that I would have removed the MC surround sheet metal like you did when I had everything apart. It just keeps getting in my way! Although I used an InLine Tube adjusting valve for the rear I'm not sure that I needed it, as the Fairmont's had drum brakes in the rear? John

My car has the conversion with no proportioning valve and works fine. But the inline kind are easy to install then adjust away.

Fine Lines makes it so nice, Valve bolts right to master cyclinder, they supply lines and all. Super nice set-up!!

I have the Wilwood disc and used porportioning valves on both cars. Never have messed with them and I race my cars. No front stabilizer bars because of headers and don't know there not there.

Although I have pedal, I would like to have it higher and more firm. Does anyone have a modified setup for pressure bleeding these dual master cylinders in the limited space? It just doesn't work with my wife helping me anymore! John

Scarebird 10 year Brake Info
I think this is what you are looking for? Used the Ford Fairmont MC but added a wedge at firewall to make it horizontal.
John, 9 years goes quick! |

What master cylinder part number did you use? I bought the NM1764 and it doesn't fit. The mounting holes are to close together 3.25. They should be 3.5".

use this at the receiving end:
http://www.harborfreight.com/brake-f...der-92924.html works very well, buy a gallon of fluid and go. best to get a couple extra bleed screws and drill them thru. use them to bleed so caliper threads do not leak air. |
