    Q:
    How do you disconnect the retainer clip from the clutch master cylinder pushrod without damaging the Clutch Slave Cylinder for the 1995 Chevrolet Blazer? Posted by Gregg H.
    A:
    Start by raising the vehicle and securely supporting it on jackstands. For 1994 and 1995 models, disconnect the hydraulic line from the release cylinder by removing the cotter pin and pulling the line straight off its fitting. Then, remove the two release cylinder mounting nuts and detach the release cylinder. You can Select Your Vehicle to see complete installation and repair tips.
