The Triumph Dolomite Club - Discussion Forum

Ok thanks guys

Tony

I'm off to the reconditioners before the weekend and have some core OE sprint master cylinders here. Would there be demand for OE sleeved in stainless? I'd imagine the cost would work out to be similar to the single line brake master cylinders...

I'd be interested!

A further update for those who are interested,I have just bought off ebay a brand new "sprint" clutch master cylinder,at a reasonable price.
When it came today,it is a Landrover one,made by Britpart,and it is .625 bore, and for a remote resovior,both inlet and outlet pipes are the same size,but as yet I have not checked to make sure they are not metric.
I will let you know,and if it is correct I will post the part no.

Does the club supply a seal kit for the clutch master cylinder?

David

Interesting thread as I would have said that it fouled the servo. Clearly with Steve and Alun saying it fits, my memory is failing me.

When I originally bought the the Maple car the servo wasn't working so with no chance of a replacement / repair in NZ, I replaced it with one from an 1850 that was available and raced with that for years. In the meantime the clutch master was also replaced with an 1850 intergral one. Years later I was offered an recondition Sprint servo but I clearly remember having to change the clutch master back to the original setup. However, with twin 45 Dellortos it may just have been that with the larger servo I couldn't get my hand down to remove the reservoir lid!

I must admit that if your remote master doesn't have any seal issues, i would go with the suggestion of relocating the remote reservoir before replacing the master itself.

Ok,folks.I have checked the threads on the clutch mastercylinder I have bought off ebay,and they are correct 7/16 UNF.
So no need to mess about with alternatives.You can buy a BRAND NEW Sprint one off ebay,item no,
( 15221945091)for a reasonable £39,these are not New Old Stock,but new.

Thanks for the update Tony, cleaning the inner wing area is only a good thing

On the subject of clutch master cylinders, I am currently overhauling mine but unfortunately the piston appears to have seized inside the sleeve.I soaked it with wd40 and using a wooden dowel I hit it and managed to move it a bit further down but it still doesn't return. It is soaking in a bucket of diesel t the moment to see if that helps?
Does anyone have any experience of this issue or any advice?
I appreciate the options that have been discussed on this page but I would like to retain my master cylinder as per original with the remote reservoir.
Failing a successful outcome, Alun I would be interested in one of the reconditioned stainless sleeved units you are taking to the reconditioners

Thanks in advance

That product ID doesn't exist when I checked on ebay, but bought a Wilwood branded master cylinder at the NEC on Sunday, which together with the adaptor came to £31.

David, compressed air or connection to a hydraulic system can push a piston out, or some very fine wet and dry rolled to the bore diameter of the cylinder can hone the crud to a point where tapping the cylinder on a wooden block open end down can see the piston emerge.

If that doesn't work I'll post here when I get the resleeved ones back...

Alun, I tried compressed air to no avail and had tried fine wet'n'dry paper to clean the bore. The good news is that after I posted my query I went to my lockup to try again and I don't know if it was the soak in diesel but after knocking it quite few times the piston moved and I continued until I got enough purchase on the piston to finally pull it free.
Tomorrow I will check for any scratches I may have caused and clean the bore and piston with fine wet & dry before fitting new seals.
Happy days

Thankyou for your advice.

David

Thanks Tony for jogging my memory. I THINK, and by that I mean that I have to go out to the garage and dig through my box of Land Rover spares, that the Land Rover master cylinder is from a Series 2 is the same as a Sprint.

I need to check this and as soon as I can I'll pop out to the garage and dig it out, I know I have one to compare it to my OEM Sprint one, bore size etc....

If this is the case then I will have a look at getting a batch for the club spares if I can get them at the right price. There's no point in selling them to members if you can get them cheaper elsewhere, seal kits will be the same though.

Tony can you give me the Britpart part number on yours.

Thanks

Right, the Land Rover one I have has a 3/4 inch bore and I am 99% sure that it came from my old S2a.

Dollies require a 5/8 bore.
