    Installation and Repair Tips
    Q:
    How should rear drum brakes and the Brake Booster be assessed during inspection for the 1986 Acura Legend? Posted by Customer
    A:
    During inspection, rear drum brakes should be assessed by removing them and checking the lining thickness, contamination, and overall condition. Ensure proper installation of shoe return and hold-down springs and the adjusting mechanism. Examine wheel cylinders for leakage and drums for cracks or imperfections, addressing them accordingly.
