Q) What are the advantages of sleeved cylinders?
A) The main advantage is the replacement of the original alloy, cast iron or steel bore with a
     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.

Q) What causes brake cylinders to corrode?
A) 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.

Notice the differences between the two bores of the wheel cylinder bodies.
The one on the left is beginning to show signs of wear and corrosion.
The pit marks, if left, 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.


Q) Can this corrosion be removed by honing?
A) 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

Q) Does the trade recognise sleeved cylinders as an accepted repair procedure?
A) 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
Since 1956, Power Brakes has successfully sleeved and remanufactured tens of
     thousands of cylinders.

Q) So in summary, what's in it for me?
A) 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.
Power Brakes has an extensive range of repair kits, individual parts and information to assist

     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.
