2ND Coast Brake: Disassembly
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1992 Geo Prizm, 1991 Toyota MR2, 1991 Toyota Corolla, 1991 Geo Prizm, and 1990 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- Prior to disassembly, check brake piston stroke. Apply paint to piston rod at point rod meets transaxle case. Apply compressed air to oil passage and measure piston stroke using Wire Gauge Set (09240-00020). Piston stroke should be .059-.118" (1.50-3.00 mm). See Figure.
- If piston stroke exceeds specification, check brake band. If brake band is serviceable but piston rod stroke is not within specification, select NEW piston rod. Piston rod is available in lengths of 2.811" (71.40 mm) and 2.870" (72.90 mm).
- Remove oil seal ring from piston. Remove "E" ring while pushing piston with needle-nose pliers. Remove spring, washer and piston rod. See Figure.
