I have to replace my rear brake light switch. What tools (size socket) are needed. Also will I loose much brake fluid when replacing?
If you depress the brake pedal slightly, the master cyclinder port will be covered up by the the piston movement and you will only loose very little fluid. Just be carefull because when you break open the hydraulic system, it will initially be under a slight pressure. This will keep your master cyclinder from gravity bleeding dry.
I may be wrong but I would think having the master cylinder gravity drain would allow less of a chance of air getting into the system while you swap out the switch. I would actually have a helper push on the pedal very slowly to create positive fluid flow thereby preventing air from being pulled in.
Yes, no , maybe?
