Having a blast replacing my brake light pressure switches on the master cylinder.
The front switch is not too bad, the rear switch is a royal pain in the butt.
To make thing more fun, the old switches need a 22 mm wrench, and the new ones need a 24 mm wrench.
The front switch is easy with a deep 22 mm socket. Just remove all the stuff in the way, and the deep socket makes it simple to remove and replace.
The rear one has the air controller box in the way to prevent using a socket. My only choice was a open end wrench. Again, 22 to remove the old switch, and a 24 to get the new one back on. And it was turn a little bit, turn the wrench over, and turn a little more and turn it over and do it again. The brake line prevents using the box end on the wrench.
My brake lights are no longer stuck on.
