Q & A

What's in the Box

Whether you are restoring a classic or building yourself a traditional hot rod, you need a set of our new stainless steel sleeved wheel cylinders. We start with all new casting, install corrosion resistant stainless steel sleeves with news pistons, cups and seals. Each cylinder has two bore sizes just as the originals did.

Features a 7/16"-20 straight thread inlet. To adapt to an AN# 3 brake line, use fitting # 617-4132 along with crush washer # 617-3513. Bleeder is threaded 3/8"-24.

Notes

WARNING - These parts are designed to operate under hydraulic fluid pressure. To insure that there is no damage to the seals avoid the temptation to push inward on the cylinder dust covers and pucks with your fingers prior to installation (when there is no fluid in the cylinders). With lack of fluid in the cylinder, this action can dislodge the internal rubber cup piston seals from the installed position. Failure of the internal seal to seat correctly can produce a wheel cylinder fluid leak which allows air to enter the lines and disable the brake system. Please follow brake service instructions from an accepted automotive service manual.

Just what I needed

January 23, 2010
The wheel cylinders were to replace retrofit units from somewhere else. These fit my 1936 Ford Coupe perfectly with no installation problems. It solved the problem of the previous units sticking. I would recommend them to anyone. [...]

What size master cylinder bore would recommended for use with these wheel cylinders? I have a '32 roadster with Buick drums in the front and drums in the rear.

The most commonly used master cylinder with the 39-48 wheel cylinders is a 1” bore size. Some of the original master cylinders were slightly over 1” but had a longer pedal to increase pedal ratio. For hot rod use a 1” bore is recommended along with a 6.5 to 1 pedal ratio or higher.

Mount patterns are not readily available. We do have available the bore size for the front at 1 ¼” and available in left or right and requiring 7/16 x 20 straight thread fittings. The rear are 1 1/8” bore and requiring the same fitting. Mounting dimensions have been requested and available on our website soon as available.
