PeteH Posted February 3 Report Share Posted February 3 So do we now know the answer to "dodgy" knees? (the other post?) needing refurbishment?. ie; the lack of Servo assist on small chassis Triumph`s. could there be a case for a "class action"? do we know who to sue?🤣 Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 3 Report Share Posted February 3 (edited) Sadly late GT6 mk3 has servo as standard, so no to small chassis discrimination! Did I mention that already? Wonderful thing Alzheimer's, everyday so many new friends! Doug Edited February 3 by dougbgt6 Link to comment Share on other sites More sharing options...
Wagger Posted February 3 Report Share Posted February 3 Yes, my car has the large diameter master cylinder. Best for you to retain the servo I guess. Two years ago the serpentine belt failed on my modern. I managed three miles to home with heavy steering and poor brakes. Plus the battery was discharging at some 25 amps driving the fuel pumps etc. Link to comment Share on other sites More sharing options...
johny Posted February 3 Report Share Posted February 3 Ive also gone to the larger bore MC on my Vitesse but without a servo although I might consider having one at a later stage... Link to comment Share on other sites More sharing options...

Not so much that for me, although I do drive with no shoes on or slip on beach shoes, I find the proximity of the throttle to the brake pedal worse. Maybe it`s just my size 12`s. No servo on my 2.5 Vitesse and with properly working and setup brakes, with Mintex 1144 pads I find the brakes pretty good. S 1 Link to comment Share on other sites More sharing options...

johny Posted February 3 Report Share Posted February 3 Ive gone for something like this 3/4" bore: Clutch Master Cylinder For Land Rover Defender 300tdi Td5 & Series 3 STC500100 | eBay Theyre available in different makes and prices and Ive fitted a reservoir extender but they also come reservoirless so you can fit one of the larger plastic ones... Tightens up the pedal but perhaps needs a little more effort so would go great with a servo🤔 1 Link to comment Share on other sites More sharing options...
Steve P Posted February 3 Report Share Posted February 3 I fitted an after market "upgraded " master cylinder to my 13/60, it made it much worse needing more leg. Now fitted an original Vitesse cylinder and 4 pot callipers which is a 100% improvement on the type 14`s. S Link to comment Share on other sites More sharing options...
Iain T Posted February 3 Report Share Posted February 3 (edited) A larger bore displaces more fluid but at less pressure. Don't we need a smaller diameter to reduce pedal force? However it would result in more pedal stroke to displace enough fluid. Iain Edited February 3 by Iain T Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 3 Report Share Posted February 3 While searching for the cause of my new servo not working I suspected the MC and replaced it with a spare which had a smaller bore, just 1/4" less. This increased the stroke by 2" and couldn't be improved by extensive bleeding. I put the old one back. Turned out the servo internals had been incorrectly/poorly assembled. I took it apart, cleaned it up and reassembled. Now it has an external one way valve as well as an internal, just to make sure. Chinese junk.

I take it even with the correctly assembled MC the stroke wouldn't have improved as its purely due to moving a volume of fluid. Iain Link to comment Share on other sites More sharing options...

NOS asbestos pads a great help as well... Link to comment Share on other sites More sharing options...

68vitesse Posted February 3 Report Share Posted February 3 I regularly drive my Vitesse while wearing size 12 walking boots, don't think a larger brake pedal would be a good idea. Regards Paul. Link to comment Share on other sites More sharing options...

Regards Paul. You`ve done well. I tried moving my 13/60 wearing size 9 Rigger Boots, and nearly ran it into the bench in the garage!. Went for the brake and got acclerator first. Someone posted?, about fitting the drop down accelerator (Spitfire?) to a Herald, don`t know if that would give increased clearance?. Pete Link to comment Share on other sites More sharing options...
Wagger Posted February 4 Report Share Posted February 4 I fitted a drop down accelerator pedal as GT6. no confusion now and it is much smoother with more travel on the throttle. Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 4 Report Share Posted February 4 I have size 8, but they're wide. I have one pair of shoes that are too wide for the GT6, either catching the foot rest and clutch or clutch and brake. Doug Link to comment Share on other sites More sharing options...
