Clutch Adjustment?

[ham204]

On a slightly different tangent I have ordered a vacuum bleeder to do some brake work. I'll be interested to see how I get on as actually it could work very well for the clutch hydraulics. You attach it to an air line and another bit to the bleed nipple and then it sucks fresh fluid through. For the Mazda you can't fit the eezebleed to the cap and I can't always rely on the MK1 Wife to assist with some pedal work. I thought for £20 it was worth a shot.

On whether the remote bleed being high is a problem, I would say no. If you're forcing air out of the reservoir whilst using either your foot or an eezebleed then the position of the bleed nipple is the least of your problems.

I think you need a bottle between the bleed valve and vacuum bleeder

[SprintMWU773V]

No not for the air operated ones. You need the bottle (comes with) the hand operated vacuum type ones. I did consider one of these but then thought it might be advantageous to have one with a bit more oomph plus I have a compressor so no shortage of free air. The one which arrived today looks a bit like a spray gun and it collects the waste fluid in a bottle underneath.

To conclude the vacuum thing is s##t.

On close inspection of a few Sprints at the MG&Triumph Show in Stoneleigh I have now realised that the PO or earlier have replaced the standard master cylinder with what looks like a MC that you would find in a Spitfire.

Would a different MC have an effect on the way the clutch operates?

[Jon Tilson]

The crucial thing on the master is the bore diameter which IIRC is 0.625" and goes with again IIRC a 7/8" bore slave.

A sprint would originally have had a master cylinder with a remote reservoir attached to the suspension turret. Quite a few later 1850's also had this. Of late this type of cylinder became rare so it could well have been replaced with an integral reservoir type but
I doubt it was a Spitfire one as these have an angled reservoir. Most likely one from another dolomite or Land Rover.

Jon, you're right - its not the angled type but sits 90 degrees but is about the same size.

[ham204]

Update: the MC turns out to be 3/4" and I've been told that replacing it with the standard 5/8" should improve clutch take up. New MC on the way, hopefully that's one problem now resolved.

[Jon Tilson]

Aha...thought I remembered the duplication from f-b.

Glad you have it sorted.

are you based in harrow ?

There was a guy at the TDC stand in Stoneleigh who appears to have cornered the market for Sprint brake reservoirs as he apparently has about 24 of them ( less one as I bought one)
