Stainless Steel Sleeved, New Brake & Clutch Cylinders

For lots of reasons but mainly because the rubber seals wear over time. They can also lose their elasticity. They can swell with contaminated fluids or oil and can be damaged when working in a scored or corroded cylinder.

Modern brake fluids are a mix of chemicals designed to achieve the high boiling point necessary to meet the demands of modern disc brakes. Brake fluid is also hygroscopic, which means that it attracts moisture from the atmosphere.

Moisture absorbed into the brake fluid starts the bore corroding and significantly lowers the boiling point of the fluid.

Usually the corrosion is far too deep, and honing just makes the cylinder oversize. This additional piston clearance causes instability of the piston, and damage and premature failure of the rubber seals.


Notice the differences between the two bores of the wheel cylinder bodies.
The one on the left shows signs of wear and corrosion.
The pit marks will only cause the cylinder to leak and eventually fail.
The cylinder on the right has a stainless steel sleeve that provides a permanent ideal surface for the rubber seals.

By precision boring the worn cylinder and pressing in a new non-corrosive stainless steel sleeve.
This sleeve resists the corrosive attack of the unstable nature of the brake fluid used in braking systems today. It also provides a permanent ideal surface for the hard working rubber seals. The cylinder bore is now better than new.

Another advantage is that when certain cylinders are very expensive or are no longer available new, sleeving becomes an attractive alternative.

We also have a moral responsibility to conserve the world's precious resources by recycling, rather than carelessly junking complex castings.

Yes it does. Hydraulic cylinders are currently being sleeved all over the world. Government departments, that have the highest standards to maintain, are making use of stainless steel cylinders. Since 1956, Power Brakes has successfully sleeved and remanufactured tens of thousands of cylinders.

A sleeved cylinder is superior to a new cylinder because of its non-corrosive bore. This service is particularly valuable when new cylinders are excessive in price or are no longer available.
Our sleeved cylinders have a proven record of a long life and are ideal for classic cars that are used only on rare occasions.

Note: Please pack your cylinders so that they can't bounce around in the box, or they may punch through the wall of the carton. Use enough foam, crumpled newspaper, bubble wrap or other packing material to fill the box.

Be sure to drain any brake fluid from assembled cylinders. If cylinders are wet, double wrap them in plastic bags so they do not leak into the packaging.

We carry a huge range of new cylinders at very competitive prices. Phone us to check on price and availability on  (08) 82610888 .
