martyn wright Posted October 7, 2020 Report Share Posted October 7, 2020 Hi All! Just fitted and went to "Bleed" the brakes to find that both Master Cylinders are seized and I cannot get the pistons out, so I contacted the Triumph-recycler and purchased 2 x Complete Cylinders with Push-Rods for £57. Delivered! Cheers Martyn Link to comment Share on other sites More sharing options...
Clive Posted October 7, 2020 Report Share Posted October 7, 2020 Are those the correct bore versions, or the landrover 3/4 bore type? (some sellers call them"uprated" !!!) And the brake cylinder, it does have the larger reservoir? (Don't throw the old ones away just yet) Link to comment Share on other sites More sharing options...

Pete Lewis Posted October 7, 2020 Report Share Posted October 7, 2020 you would find lots of 3/4bore witha upright reservoir for around £22 these are bigger than the 0,7 and what you get is less pedal travel acompanied by a higher pedal load input , but makes an economical replacement if you dont mind not being exact OE spec. the angle of the resv is not really a problem , just dont fill to the brim Pete Link to comment Share on other sites More sharing options...
martyn wright Posted October 7, 2020 Author Report Share Posted October 7, 2020 Hi Pete, I meant to have amended my last message: Bore is 0.750 the standard is 0.625! 0.750 will push 20% more fluid per distance pedal travelled than a 0.625 cylinder.

No,the bore is 20% bigger. That is a 44% increase in bore area/fluid moved, not insignificant. They are a landrover aftermarket cylinder. Nothing inherently wrong with them, but make sure you like the pedal feel. If you have a brake servo it will be OK, but without? Link to comment Share on other sites More sharing options...
johny Posted October 7, 2020 Report Share Posted October 7, 2020 Ive got one installed without servo and like it but thats on a 2L and I believe the brakes are different from the 1600.... Link to comment Share on other sites More sharing options...
Clive Posted October 7, 2020 Report Share Posted October 7, 2020 Yes, 2L is 0.7 bore brake master,so only a 14% increase. I tried a 0.75 master on spitfire (GT6/Vit front calipers) and found the brakes a bit wooden. A change to 0.70 feels better. If I could be certain I wouldn't run out of travel, I would go to 0.625, but not worth the risk. (I do have rear discs, so more fluid movement than drum rears, but only a smidge) Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 7, 2020 Report Share Posted October 7, 2020 the 0.625 " went up to 0,7 when larger capacity calipers appeared not looked it that was T14 or T16 s not remember what was on my 1600 as we upped from t12s to type 16 and 0.7" Mcyl to match + servo |+ 1144 pads she was a hoot to drive but needed some stopping pete Link to comment Share on other sites More sharing options...
martyn wright Posted October 7, 2020 Author Report Share Posted October 7, 2020 Well Gents! Theyre on there way, so when I have fitted them and actually got the car running I will let you know? Cheers Martyn Link to comment Share on other sites More sharing options...
NonMember Posted October 7, 2020 Report Share Posted October 7, 2020 Back in the distant past we fitted a Vitesse 2L master (0.7 bore) to a Herald 13/60 with type 14s. The pedal was rock solid and needed a lot of pressure. Would have worked well with a servo, I suppose. I don't think I'd want 0.75 bore with type 12s.
