Changing rear brake light switch but not clear on how to access switch without disturbing master cylinder. Have removed plastic cover and large structural aluminum plate (muffler is held by this plate, use 10mm hex). Also removed dust cover under brake pedal. Master cylinder is attached to aluminum plate (along with brake pedal and light switch). Noticed that brake fluid canister is above and attached to frame with supply hose leading to master cylinder. Is it possible to access the brake light switch without disturbing master cylinder? Have not even gotten close the infamous springs as yet. Any help is appreciated.
