Scion 31420-20070 Cylinder Assy, Clutch Master

To remove the components, first disconnect the negative cable from the battery. Next, take off the driver's side knee bolster and disconnect the pushrod from the top of the clutch pedal, which is secured with a clevis pin; remove the clip to release the pushrod. Then, remove the brake master cylinder and the power brake booster. Disconnect the hydraulic line at the clutch master cylinder using a flare-nut wrench to avoid damaging the fitting, and have rags ready to catch any fluid that may leak, ensuring that brake fluid does not contact paint. From beneath the dash, remove the nuts attaching the master cylinder to the firewall and take out the master cylinder carefully to avoid spilling fluid. For installation, position the master cylinder on the firewall and install the mounting nuts finger-tight. Connect the hydraulic line to the master cylinder, ensuring not to cross-thread the fitting, and then securely tighten the mounting nuts and hydraulic line fitting. Reconnect the pushrod to the clutch pedal, install the power brake booster and master cylinder, and connect the clutch fluid feed line to the brake fluid reservoir. Fill the brake fluid reservoir with the appropriate brake fluid and bleed both the clutch and brake systems. Finally, check the clutch pedal height and free-play.

Disconnect the cable from the negative terminal of the battery.
