sprint clutch master cylinder

#1 Post by dailysprinter »

Has anyone tried the repro one that Abingdon parts do at £42.50?

I got one I cannot get the pison out of ny old, it stuck right in and I've tried heat already, I think its scrap.

Are there any other reasonably priced new ones about?

any girling cyinder with vertical mounts and remote or plastic reservoir and the same bore. Ditch the reservoir and use your old one.

You can use a standard dolly one if totally stuck. Just a bit harder to fill.

Stuck piston in master cylinder

#4 Post by Howiesprint »

Use the old hydraulic method to get the piston out of your old one. I did this with a Brake Master cylinder that i thought was scrap.

Find some bolts with the same thread that will screw into the pipe inlet/outlet holes on the cylinder. Screw one bolt into the outlet hole fairly tight and then fill the inlet hole up with grease. Screw second bolt into inlet hole to force grease into cylinder. Grease will force piston back out. Will have to fill hole with grease and screw bolt in a number of times to get the piston right out but it worked a treat for me. Just clean grease out with parrifin when finished

They are cheap, girling 3/4" diametre, they fit right in place, and you can find some new one for cheap on e-Bay.

I bought mine for 10£ iirc.

Push the piston down the bore as far as it will go and clean it with brake fluid and 1000 grade wet and dry. Its prpbably sticking on the circlip groove. You can be a bit more abrasive past the rubber sealing surface..ie a piston length.
Try an airline...or another cylinder back to back...or a tyre pump and an eezibleed.

If I could find a new cylinder for a tenner I'd keep a few 4 spares
