"Who will rid me of this turbulent flippin 306 brake pain!?"

What sensation is it? Might be worth trying to preserve it.

Scoots, I've got a Mityvac pressure bleeder, want to borrow it for a week?

 

No pressure (pun intended) but I need to know this morning so I can post it to you, otherwise I'm out of the country for a week. PM me your address

 

It won't fix the caliper with the snapped nipple, but it'll do the rest of the system very well so the broken one should be ok if you bleed it at the brake hose.

 

For the other bleed nipples, don't open them up too far to bleed; a quarter of a turn should do it. Any more and you'll be drawing air between the threads, not through the nipple hole

having made brake systems up many times...I have never had to bleed a master cylinder ever, in fact i didn't know you could....... is the car level or higher at the front?...i always make sure it's higher at the front so any air has to be at the front, also try taking the caliper off and position it so the hose union is the highest point, not just nearly the highest.

The Mityvac is a grand tool, bit like an Ezibleed but useful where the adaptor won't fit your reservoir. I used it on the Land Rover, Ginetta and on my motorbikes too.

 

- Crack open the bleed nipple a bit just to make sure it moves, then close it off. Push the clear hose over the nipple and push the white plastic loop over the whole lot to make an airtight seal. If it doesn't fit, use a plastic cable tie or something. Remember to leave room for the spanner.

 

- Pump the thing about 10 or 20 times, after about 20 it doesn't get any firmer so that's as much vacuum as you'll get.

 

- Open the bleed nipple and all the brake fluid and bubbles will get sucked out. Close the bleed nipple before it runs out of pressure, then pump the thing again. Repeat until you remember to check the brake fluid reservoir has still got fluid in it.

 

As said above, make sure the drum brakes are adjusted first, and start with the wheel furthest away from the master cylinder, working your way to the closest.

 

If you're particularly paranoid, before you start you can unscrew the bleed nipple and put PTFE tape over the threads. Be careful not to put too much, but it'll stop them seizing up again. To be honest, most have seized or snapped because they just haven't been opened for 10 years.

Issues I have had before are the seals going with the pedal pushing method hence always using an Ezi Bleed. Pretty cheap as well ..
