This is the same brass casting used on the 1977 MG Midget. The piston is different and the valve is mounted with the securing bolt down. Also, the "cap" has a brake line fitting that goes to the left front caliper. The one in this video is blank. This video helped me by saying that two of the o-rings are not used. Huge help.
Same as mine! Delved into a lot of questions to others, I went with the larger o-rings (11/32 OD rather than the 5/16 OD) the Shuttle OD is 5/16ths. o-rings we're snug but got them to seat buy pushing the o-ring past the pressure switch hole with a small punch because of the bore to get it to pass to the back.!
Thanks for linking this to my question on 6-pack. I think that I will try to find a 'cap' to put in place of the switch. Failing that, I have a great guide now. I even have compressed air ;)
Good to hear. Yes you can plug if you wish. It is a safety item though. I think it’s course thread so you may need a good copper washer with the temp bolt to seal.
Got a 77 Midget, had to replace the o-rings on the 'shuttle' also. Mine is a little different, the shuttle has a spring captured by C clips on one end followed by the end cap, then the left front brake line threads in the end of the nut. Definitely a bugger as you well know to install. I do have a question if I may, .... how did you bleed the brakes? Vacuum at the wheel cylinder bleeder?... Buddy system ?... or gravity feed by just opening 1 bleeder at a time waiting for the fluid to drip? Thanks, appreciate the video.
All those methods will work. For many years I used my vacuum puller bleeder. I did this because it’s a one person job. Some people use an old brake master cap and rig an air connection to push fluid. I didn’t have an extra cap to do that. Gravity works but I would only do that if you have a problem bleeding as last resort. Currently I’m old school. I place a 2x4 scrap lumber behind brake pedal and do the up/down thing with the wife. I found the lines flushed out much quicker this way. Board is so the pedal does not collapses to the floor and damage the internal o rings in master cylinder.
@@DIYHelp brilliant idea on the 2x4 ! Can't get my rears to bleed due to the rear hose failed.! ALL components are replaced, just waiting on a new master cylinder. I will bench bleed first BEFORE installing it, then hopefully all will go well. Thanks for the reply!

That was helpful. Thanks!
That’s great. Hope it goes well for you.
