Brake pump overhaul specifications
After washing all the parts with a specific solvent, never use oil, petrol or solvents that have a corrosive
effect on the rubber, check that:
The pump body does not show signs of internal damage or corrosion as this may result in sealing ring
or piston failure; the latter must also be replaced if worn or scratched.
The rubber parts in the piston and the valve are not dilated or damaged as this most likely leads to poor
braking.
The piston return spring is in good condition.
The passages connecting the pump tank to the pump body are not clogged or dirty.
Removing brake fluid reservoir and pump from chassis
