clutch slave cylinder bleeding tips?

[oxopop]

just wondering if there are any specific hints or tips for bleeding the clutch slave on my sons 1979 1500 hl? or is it a standard type procedure.thanks

Standard bleeding procedures apply.
The 1500 slave is easy enough to get to from underneath the car.

The way I have done mine in the past is to use a gunsons easiblled that uses pressure off the spare tyre to push the fluid through and at the same time pump the pedal a few times as I have found that air can get trapped in the m/cyl which needs removal by pumping the pedal as well. If you can get the slave cyl off from underneath and leave it connected to the hydraulic pipe and raise it into the engine compartment and bleed it that way as that ensures all the air is removed.

I would recommend, as previously suggested, take the slave cylinder off and hold it at an angle in the engine compartment when you bleed it to ensure all the air is removed from it.

I did this for a friend after his local garage had changed most parts of the clutch hydralics and could not sort out why the system was not working.

or you can jack up teh rear of the car instead of the front...

Bleed screw must be highest point in slave to avoid air bubble.

Just in case you havn't done it yet but back bleeding is the best way and it's very easy.
It is what's often done on bikes when you're fighting gravity to get rid of the air (a bit like you are on the Sprint!). Anyway, a summary from a previous description I gave.

What you need:
1. 100ml plastic syringe (~£4 inc. postage from ebay)
2. piece of pipe to go on end of syringe and attach to bleed nipple (~10-15cm fine)

Instructions:
i) Push one end of pipe onto syringe
ii) Suck 100ml of new brake fluid into syringe via pipe
iii) Lie under car (which must be on axle stands or ramps) & undo bleed nipple
iv) push free end of pipe over nipple (must be air tight fit)
v) force fluid up into (empty) master using syringe and tighten bleed nipple
vi) top up reservoir if necessary

Note that on the Sprint you must force piston to back of slave cylinder (using screwdriver against clutch housing) for the entire duration of bleeding i.e until you've tightened up bleed nipple. Don't know on 1500.

You will need to pump pedal a couple of times to move the piston to correct location in slave.
