6.3.7. Dismantling and assembly of a back drum-type brake
Assembly of the piston and sealing ring of the piston
Before assembly wash out the piston and the cylinder alcohol or applied brake liquid.
Grease with brake liquid a sealing ring of the piston and the special tool.
Applied brake liquid: D0T3 or D0T4.
Put on a sealing ring of the piston a special opravka so that the sharp edge was turned upward and then, lowering on an opravka down, establish it in a piston flute.
To avoid twisting or a distortion of a sealing ring of the piston at installation, lower it slowly and accurately, one movement without stops.
