1995 Toyota Corolla Question: Necessary to remove brake booster to replace clutch master cylinder?

 

Question

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.
