Clean the brake assembly – use brake cleaner to remove dust and debris.
Disconnect the brake line – from the back of the old wheel cylinder using a flare nut wrench. Cap the line.
Remove the old wheel cylinder – unbolt the two mounting bolts from the backing plate.
Clean the backing plate mounting surface – remove old gasket/sealant.
Compare new cylinder with old – verify bore size, bolt spacing, and port orientation.
Install new wheel cylinder – apply a thin film of brake grease to the mounting flange. Bolt to backing plate. Torque bolts to specifiion (typically 10-15 Nm).
Reconnect the brake line – hand-start, then tighten with flare nut wrench. Do not cross-thread.
Reinstall brake shoes and hardware – ensure pushrods engage properly.
Reinstall brake drum and wheel – adjust shoes if needed.
Bleed the brake system – start from the wheel farthest from the master cylinder.
Check for leaks – inspect the new cylinder and line fitting.
Test drive – ensure proper braking and no pulling.
