Old MC out.
Whomever designed the mounting arrangement for the LHD Twink brake master should be strenuously talked to. Needed to destroy/modify an “S” wrench (harbor freight...so not too painful...) to get that infernal top nut…which ended up unscrewing the stud thru the spacer into the frame anyway. -10 points for where Lotus put the cylinder…+5 for welding nuts on the inside of the frame…because access to the back is well-nigh impossible...
Hint: if you are going to remove this thing…undo the nuts t from the center of the car, not thru the wheel arch. you have a bit more room to actually get a wrench on that top nut after you disconnect the bundy pipes. Bottom is a doddle. My modified wrench was just the ticket. If it works, it can't be ugly, right?
Going in? A Spitfire dual circuit master. yeah, That means building jumpers to change location of the outlet ports. Dry fit it, and lines up ok.
Used the brake piston actuator rod (the one with the bell end and threaded shaft) from the old cylinder and took apart the cupped washer and snap ring from new cylinder…threaded all together using the old domed actuator rod in the new cylinder…domed washer from new cylinder...snapped the snap ring back in place…it all fits together. Yay for me.
Instead of using nylocs when I put it back together…use stainless 5/16-24 nut and lock washer plus flat washer combo. Little anti-seize….should be ok.
Cleaned up the threads of the pins that mount the MC thru the adapter to the front of the frame. 5/16x24, if anyone is keeping track.
