Default Clutch Master cylinder

Actually Thursday, not today but have successfully swapped out the old one for one of DMGRS's "left hand drive" ones where you use your existing pipework.

Symptoms were my clutch bite point was getting steadily nearer the floor and it felt difficult to change gear.

I was praying that it was the master, not the slave.

First off the plastic collar that splits the quick release under the battery was missing .

Turns out that there's a "spare" plastic collar on the one from DMGRS so I successfully used that .

Decided to remove the clutch pedal to get better access and sight. Fortunately that comes off easily and quickly. A couple of clips, pop off the master shaft and she slides off and out. Just beware the spring.

The master is in a stupid place but it's not actually difficult as such. Just time consuming and awkward. I sucked out the fluid with a syringe as I didn't fancy it all over the carpets and it wasn't pretty. A sort of grey/black colour. Nothing like the clear, new fluid.

The two little (8mm head) bolts holding the master in place are a bit of a faff but OK with some patience and a short 8mm socket.

Pulling some hydraulic pipe through the bulkhead was fun. But worth it in the end for ease of access to get the split pin and roll pin out.

The new master slotted straight in and was soon ready for bleeding.

Using a Gunson's Easybleed I flushed about 300-400 ml of fresh fluid through the new master & pipework then connected up the slave and flushed a further 300-400ml through the whole lot. It's really to do easy with pressured bleeding. The last thing I want is any muck/debris from the old master/pipework to end up in the slave.

The Easybleed runs at 20psi max. so remember to pump up your spare tyre if that's what you used.

And the result, a whole different biting point. Gear changing is now lovely and it's the best clutch feeling I've had on any of the Rover's I've owned

As an aside I seem to have cured an intermittent cruise fault where it would disconnect completely when, say, coming off a motorway, onto a roundabout. I'd initially put it down to the brake switch but having to reset the clutch switch appears to have cured it. Fingers crossed.

Thanks for all the help, particularly from DMGRS for getting the unit to me pronto, Colvert & Mike Noc for suggestions about the missing plastic collar and, of course, all the threads and numerous hints and tips on the forum.

Cheers.
