Cleaning the brake cylinder. Photo by E. Wilde, 2007 Dec 6.

The brake cylinder can be cleaned up using a wire wheel and sand blaster. Although the cylinders are aluminum and not subject to rusting, aluminum cancer is still an issue. A coat or two of paint couldn't hurt. Photo by E. Wilde, 2007 Dec 6.

Painting brake cylinder parts. Photo by E. Wilde, 2007 Dec 6.   A coat of primer (red metal primer for the steel, zinc chromate for the aluminum) and a top coat (basic black) is applied to the cleaned brake cylinder parts, prior to reassembly. The paint is kept out of the cylinder by masking or blanking plates. Photo by E. Wilde, 2007 Dec 6.

A stainless steel Brake Cylinder Boot Clamping Band can be easily applied to the boot using readily-available tools (a screwdriver and a pair of pliers to pull on the end of the band). The parts page has these bands for sale. Photo by E. Wilde, 2008 Jan 4.

Before and after photo, showing a refurbished cylinder next to an unrebuilt cylinder. New bolts were applied from a Brake Cylinder Assembly kit and the boot was fastened using a Brake Cylinder Boot Clamping Band, as shown in the previous photo. Both of these items can be ordered from the parts page. Photo by Eric Wilde, 2007 Dec 21.   Brake cylinder before and after. Photo by E. Wilde, 2007 Dec 25.
