Rebuilding locker masters

Post by MTPinz »

Going in deep!

My 710 came with a broken rear locker selector and the piston seized in it's master cylinder so I decided to rebuild all three at the same time.

The manual says that the piston and cylinders are a matched tolerance set so I'm keeping everything separate. I'll mic them out once everything is cleaned up just for personal reference.
It also mentioned not to hone the bores? How about just some light scuffing with some fine Scotch Brite or something?

Any BTDT tricks for getting the new seal on the piston? Just lube it and stretch it over?

Well that was easier than I thought it was going to be. I rebuilt all three master cylinders for the lockers, fixed the lever assembly with the 'upgraded' bolt addition, and took care of the rusting mounting box. I went ahead and cleaned the reservoir and replaced the rubber T's coming off it for good measure too.

With how rusty this rig is in places, I was very surprised that when I went to bleed it none of the bleeders on the slaves stripped. I couldn't believe my luck! I replaced them with bright shiny new ones anyways.
On to the next item on the list...the fuel system!

Nice. Which brake fluid did you use to refill?
