Re: Rear drum brakes
The Brakes can be cleaned using a spray bottle filled with soapy water and a clean solvent brush. Spray, then brush. Spray again. Repeat until the dust is removed. Capture the runoff in a catch pan. Allow the water to evaporate and clean up the dust. Most brake friction components (brake pads, shoes) haven't used asbestos for some time but contrary to popular opinion it hasn't been phased out completely. Always wear protection (breathing masks and gloves) when working on these systems. I wouldn't use the paper filters that do not seal on your face, the dust will get past the edges.
Brake Clean is a Non-Chlorinated Hydrocarbon volatile fluid. It is expensive. It is also flammable and can cause nerve damage with repeated exposure. Use in an open area, do not allow fumes to concentrate.
