Troubleshooting
Master cylinder still leaks after rebuild
Ensure all seals were installed correctly and the piston moved smoothly. Check the cylinder bore for any imperfections missed during inspection.
Brake pedal feels spongy
The system may not be fully bled. Re-bleed the master cylinder and brake lines. Ensure no air is trapped.
Brake pedal doesn't return properly
Check that the spring and pushrod are installed correctly and are not binding. Ensure external linkage is not obstructing return.
Difficulty installing new seals
Lubricate seals with clean brake fluid before installation. Avoid forcing seals; ensure they are seated properly.
