(Feeler) Power Brake Master Delete adapter / Wilwood manual (7/8") tandem Mater Cylinder
Friday, September 12, 2014 6:44 AM
This feeler is for an adapter plate to delete the stock power master cylinder, and replace it with a Wilwood 7/8" tandem master cylinder.


The master cylinder in question is the "Wilwood Aluminum Tandem Master Cylinder w/ Pushrod."

There are three versions available.
Aluminum Tandem Master Cylinder w/ Pushrod with Plain Finish - Product Number: 260-9439 - Price: $215.94
Aluminum Tandem Master Cylinder w/ Pushrod with Black Powder Coat - Product Number: 260-9439-BK - Price: $259.14
Aluminum Tandem Master Cylinder w/ Pushrod with Ball Brushed Finish - Product Number: 260-9439-P - Price: $259.14
Specification and Instruction Sheet Link


There are also a lot of other, cheaper, Small Block Chevy Master Cylinders that will bolt up to this plate. Below is the Wilwood Dimensions.



My adapter plate will be manufactured from T6-6061 Aluminum. The over all size is 4.5"L x 4.5"W x 0.75"T
Here is the unit modeled up in SolidWork with hardware shown for reference.



A 3D printed model was created to confirm spacing and fitment. This was before the adapter was thickened to contain the recessed bolts.




Here is a image of the adapter bolted up for mock up.



The recommended Hardware for this unit is M10 x 1.5mm Button head cap screws to hold the master cylinder to the adapter plate, and M12 x 1.75mm or 1/2" x 13 hex head socket cap screws.
I can provide these after final fitment is determined.


Prices are as follows:
1-9 People, $87.50 plus shipping.
10 or more people, $67.50 plus shipping.
Shipping will be, USPS Small flat rate box. $6.50 shipped and insured in the US of A, and $20.20 anywhere else in the world.


Added:
The push rod mounting point on the brake petal arm does need to be moved to provide appropriate braking force.

so what was the amount when you were said and done? 400-500?

I imagine this is going to require adapters, rebending the lines and blocking vacuum to the manifold...

Does the bracket come with the hardware..

With fittings and all around $400.

As of this minute no, but I can source it. If we actually get a few people I'll probably add it in.

Re-flaring the lines is the preferred method that people have done. A few have run short braided stainless lines with the correct adapters.

If you convert to a manual brake master cylinder, where are the turbo guys getting their vaccum supply??

Just a heads up, looks like you can pickup the plain master for around $200 on amazon... I've seen as low as 175 but not sure how reliable the source.

Interested.

Would you mind posting the bolt pattern on the firewall side so I can see if it fits 2nd gens?

I'm interested, count me in!

Any chance you could take a picture of what would need to be done to the pedal push rod?

I have not does this yet, this is being installed one Mike Iwans' cavalier. You could ask DaFlyinSkwirl (Pj) about what he did. I believe he posted pictures and dimensions when he did it on the "squirrel." I'll look to see if I can find the posts.

James,

The bolt holes are 87mm / 3.425" apart, and square top to bottom and side to side. Made for 1/2" or M12 hardware.

One of the stock holes is slotted a little on 3rd gens. The upper right, if I recall correctly.
