What am I doing in this corner ????

Brake Booster sticker states 'Metric Fittings'
Bought 6,8,10 and 12mm flange spanners. 7/16 fits the nipples nuts on Master Cyl !!!!
Metric Thread ????.
Old Fluid yellow, so bought Blue, DOT3. Apparently what is used on my 1985 RRC. Now can see when old fluid is out the system.
Any hints with Master Cyl ????
Undo 4 flange nut, some sort of warning light, then undo two 1/2 inch nuts holding it to Brake Booster, and it should pull clear ????
Bought some 80cc syringes to empty old fluid from MC.
Thanks.

I don't empty the tank .... I just start at the back and pump the pedal until the new fluid comes though ................ :) Starting at the furtherest corner from the MC and working closer :) Those bleeds with a one way valve make easy work of it

11mm nut size is metric, thread size is M10 x 1.0 from memory.

11 mm is close enough to 7/16 in most cases to use either.

Pulled Master cylinder apart.
Lots Of 'muddy looking liquid.
Fully cleaned an assembled, but be buggered if I can bleed them.
Seals looked ok. Light hone with 800 Wet/dry.
Plunger comes out of booster, when peddle pushed.
Its a later MC, 1995 on Alloy stamp. But just doesn't want to pump.
Have another look tomorrow, in the daylight.

All apart.
Seals appear correct way round, as per my Manual.

Also discovered, when I went to change oil,
the Z86 filter does not fit. Has been changed to Z9 at some point of its life.
Back to Repco tomorrow.
One Z86 filter, Free. PM me.

You got a vacuum bleeder? About $25 at Repco. Makes bleeding these much easier. No pumping required

No, but can look to get one.
I have a one 'person' brake bleeder kit.

I use a vacuum bleeder makes it easier. Not sure about ‘one person ‘ kits what’s in that?
