So
THESE were the fitted components then?
Quoting the seller's spiel
"Both Slave & Master cylinder are all metal uprated MG Rover versions a superior product to the original design"
I would have to disagree with this statement by the seller, these parts are not fit for purpose.
I have to say something now Martin, bleeding the clutch will make no difference whatsoever to the heaviness, it is purely down to the choice of materials employed.
You have a couple of choices, either put up with the clutch the way it currently is, i.e. noisy and heavy (noisy due to faulty thrust bearing), or replace the clutch with an LUK Repset Pro along with an LUK master cylinder.
The latter if fitted correctly will result in a light clutch which will last for at least 100000 miles if driven with mechanical sympathy.
I bought a car from a local member with one of these "uprated metal cylinder" clutches fitted, it was replaced in short order with a LUK kit.
