Does anyone know to what extent the brake booster and brake master cylinder have to be disonnected/loosened to allow for replacement of the clutch master cylinder? The edge of the booster sits over top of one ear of the clutch master cylinder. Can this operation be accomplished without diconnecting brake system fluid lines?

Is the brake master cylinder bad or the brake booster? The brake master cylinder does separate from the brake booster.

Neither one. The problem is with the manual clutch master cylinder, which is mounted partially behind the brake booster on the firewall. The brake booster will have to be moved out away from the firewall approximately 2" to allow the old clutch master cylinder mount bolt to be extracted and the new one replaced through the firewall. I'm just not sure how much "give" there may be in the brake hydraulic lines to allow the booster/master cylinder assembly to be moved out of the way.

Sorry, didn't pay attention to what I was reading. This is OE info. REMOVAL Remove brake booster. Draw out fluid with syringe. Disconnect clutch line. Using Special Service Tool (SST) 09023-00100 or equivalent, disconnect the clutch line. Use a container to catch the fluid. Torque: 15 Nm (11 ft. lbs.) . Remove lower finish panel. Remove duct heater to resister No.2. Remove clip and pin. Remove two mounting nuts and pull out master cylinder. Torque: 12 Nm (108 inch lbs.) . INSTALLATION Installation is in the reverse order of removal. INSTALLATION NOTE: After installation, bleed system and adjust clutch pedal.

The brake booster has to be removed. Repeat has to be removed. Chiltons says undo the pipe, the two mount nuts and the Clevis and out it comes. Yeah right...... I'm doing it right now and there's no way to get the clutch master cylinder out of a 94-95 corolla without moving the brake booster. I removed the four booster mounting nuts and pushed the brake pedal to the floor and that moved it about 2 inches off the firewall and eventually with great difficulty I wriggled the master cylinder out around the booster.
