Brake Master Cylinder [1968 2000 mk1]

#1 Post by Baller » Sat Jul 29, 2017 8:30 am

Hi all , after stripping down the Brake Master Cylinder I have noticed that the bore is pitted , the car has been off the road for many years , and so I think the only option is another Master. Looking on a few Triumph parts suppliers websites they don't seem available.
I did notice that the Mk2 master looks the same other than the flange has been turned at an angle rather than the bolt holes directly up and down , I'm sure this issue has come up before with other owners , anybody got any Ideas or know some one that has over come this problem with a Master Cylinder from another car maybe. All thoughts would be appreciated.

Maybe you could replace the master cylinder and servo as an assembly - from a Mk2? At least the cylinder bolt holes would align OK!

Not the ideal solution I know, but maybe worth considering.

I notice that CW lists a Mk1 cylinder but currently out of stock.

Cheers,
Mike.

Another option is to have your own cylinder bored out and resleeved with a stainless steel insert of standard bore so you can use normal seal kits in the future.

Hello Baller,

be aware that the MK 2 servo and master cylinder are largeer in diameter than the MK 1 and consequently, the space between the servo and the clutch master was increased.

I have a MK2 srvo in my MK1 and made up a spacer to mount the clutch master forward to eliminate the conflict, obviously I also had to increase the length of the push rod.

I am not familiar with what is fitted to a mark one 2000, however
I am wondering if Wilwood do a suitable brake master cylinder?
These are available new through the kit car specialists.

Hello Tony,

having been annoyed and inconvenienced in the past by washers that didn't work, this is a duplication. The nozzles are twin nozzles and angled so one nozzle does the drivers side the other the passengers. Two pumps are fitted , one for each nozzle, when all are working there are two jets on each side, but if one fails I still have one jet on each side.

Hi Alec,
I'm glad I'm not the only one peeved with the ineffectiveness of the washer jets.
I retained the single jets each side but fitted two pumps from the original single washer bottle with a separate hose from each pump to each jet, the theory being if one blocks slightly I don't get preferential flow to the other. This worked quite well but tended to blow the hose off the pump if a washer jet blocked. I then drilled the washer jets out to 1mm, so a bigger hole thus less prone to being blocked by small bits of dirt. I've now got washer jets to rival a modern car, but it empties the washer bottle rather quickly so I have to regularly top it up, two bottles may be the way forward.
