Front disc conversion

[Yadkin]

No problem this looks like a great deal, will keep all updated.

The kit came in and looks to be complete except for a proportioning valve. Do I need an adjustable P valve? This one is set for front disc/ rear drum and should work for me.

With my set-up that unit will contact the spring tower, plus I'll have to put a tee in the line to service the brake light switch. SSBC has a simple one line in, one out rear only unit, on sale directly through them for $36. #A0707

How can a two-port valve possibly do real proportioning? It can't. This #A0707 is simply a flow control valve that doesn't do half the jobs a real combination prop valve does.

It can't meter and it can't shut off the line with a rupture. No electrical warning light, either. This thing simply 'pinches off' the output to slow flow. It doesn't reduce pressure. - Dave

According to the manufacturer:

The adjustable, anodized proportioning valve regulates rear brake pressure, helping to maintain correct brake bias between front and rear brakes. The easy to turn handle with directional handles makes it simple to either increase or decrease rear brake pressure.

The center hub on the new rotors, which centers the wheel, is a different size than on the old drums. Old is 2.38", new is about 2.47". This speeds up my purchase of new wheels. Coker's "Thunderbird Wire Wheels" have a hub diameter of 2.52". They are sending me one bare wheel to test fit. I chose the wheel from a '65, since the backspace is 3.5", vs the '64 wheel which is 4".

I've been super busy at work (which is a good thing financially) so had Classic Metal in Mocksville do the conversion. Here's some photos of the finished product.

Joe did a nice job fabricating a bracket for the proportioning valve.

Looking good. Who's kit is this?

New MC and Booster required?

Hi Yadkin:

If I cannot get past this current brake issue, I am seriously considering to convert to Front Disc Brakes as well. I just checked out the conversion kit from Tom's Classics store on eBay and it looks like the way to go.

Do I need to also replace my Brake Booster and Master Cylinder? I see from your pics those look new.

Any other parts I need to consider when doing this conversion?

Regards,

If you have a single master cylinder then you should replace it with a dual master regardless of conversion to front disks. Disc brakes need a larger volume of fluid in the reservoir, so you need a compatible master.

59 Square Bird Fnt Brake Conversion

Does anyone have any feedback on the abs power brake fnt brake conversion kit . Pos/neg. they want 1095.00 plus 65.00 for the p valve . Are there better kits out there that are complete ?

Most who have done the conversion on a squarebird use Scarebird brackets and off the shelf parts such as Mustang rotors and Chevy S-10 calipers. Look in the Technical Resource Library under Disc Brake Conversion. You will find all the information there. Especially look in Marcelo's thread. You can certainly buy all-in-one kits but you will wind up paying a lot more money.
