Inline Tube - Wheel Cyl. Rebuild

One of the largest problems with classic car brakes is that your brake fluid is to be changed every few years. Brake fluid collects moisture over
time, this moisture has water in it and over long periods of time it creates rust. This means the inside of your components are slowly corroding
causing your system to loose effectiveness. This happens with anything that has fluid in it. This includes brake lines, master cylinders, wheel
cylinders, and calipers. If your car has been restored in the last few years keep up on the maintenance and change your fluid every 5 years. If
your car has never been restored and you are wondering how you can improve the brakes, the first step is changing the fluid. By getting the old
fluid out and replacing it with new fluid you eliminate all the moisture which will dramatically increase the effectiveness of the fluid increasing
hydraulic pressure by as much as 20 percent. Next you can replace the old metal brake lines which can rust from the outside from being
exposed to the elements and can also rust from the inside from trapped moisture. Before rebuilding any component you should consider the cost
and labor factor. If the component has never been replaced and it is the correct date coded part for the car it could be priceless, if the component
has already been replaced with an aftermarket piece, the time in rebuilding may not be worth the cost of a replacement. Most components have
only a few rubber seals that need to be replaced and they will be a good as new. Rebuild kits are a small fraction of the component cost but take
some labor time to install. If you are working on a driver, seals are quickly replaced in a few minutes, for a show car a more complete rebuild
may be desired. All calipers, wheel cylinders, and masters have manufacture markings and date codes specific to that year make and model.
Inline Tube replacements have the same shape and function but do not have date codes or manufacture markings. For a concourse restoration
these marking add value and detail to the final restoration. By following the steps below you can rebuild you components just like an experienced
mechanic. Inline Tube offers all the pieces of the rebuild from the rubber seals to complete caliper ready to bolt onto your classic.

These are the original Delco cylinders and they feature the Delco logo, part number, date code, and wheel cylinder inside diameter of 15/16".
The size is important when ordering the seal kit. There are many different size cylinders so if they are not marked you may need to measure the
inside diameter with a dial caliper before ordering. If the wheel cylinders are not original, they are not worth spending the time to rebuild. A
replacement wheel cylinder cost around $20.00, the rebuild kit is around $6.00 and your time is worth something.

Drain the Cylinder of as much fluid as possible. In order to get the piston out of the cylinder, leave the bleeder in place and take an air hose at
low pressure (25lbs) and insert the end in the brake line hole. When applying pressure make sure your hands are clear of the pistons that is
making its way out of the cylinder. When the piston reaches the end of the cylinder wall you will hear a pop of air pressure and the piston will be
out. If the dust boot does not come out with the piston pull it out with pliers. Remove all pieces paying attention to the order and direction the
pieces are facing, it is easy to forget and improperly install the new parts. In this assembly we will be reusing the pistons, center spring, and
cylinder body. The rubber seals will be discarded.
