- Bore size: sized for a 1.5 in wheel cylinder bore.

The wheel cylinder uses brake-fluid pressure to push its pistons outward, expanding the shoes against the drum; over time the internal cups and boots wear and can let fluid seep past. If a leaking wheel cylinder is the cause of a soft pedal or fluid-fouled shoes, this kit supplies the sealing components to rebuild it. Country of origin: China.
