Thank you Stuart.

I could not justify the cost of 2 new brake lines, just to avoid an extra connector like the ones you suggested https://automec.co.uk/collections/fittings/products/brass-inline-connectors-unf I already had new brake lines from the B/M/C to the PDWA valve, can you please confirm if the UK TR6 has a single brake circuit thank you.

 

Luke.

All markets for the TR6 have dual line circuits.

Thank you Stuart I did not know that, I know very little about the TR6 specifications.

After reading your reply I looked at a RHD TR6 brake pipe drawing and all is now clear, I can only put it down to cost why all TR6 cars did not come with a PDWA valve, because when these cars were new it would have been a good idea for safety.

I worked with what I had, and think it is better that I have a dual braking system.

Hi Peter

You are to smart for your own good  I never even thought about using bleed nipples, but I think mine looks cleaner and would have not used them, because my 3 way brake unions did not have machined faces I added hydraulic lock and sealer, although I was happy tightening a copper washer in my engineers vice would have made them hydraulic tight, I would have also been worried a younger MOT tester could get confused and worry why they were there.

No I did not have any brake components in stock, it would have been cheaper and easier to go with Stuart's suggestion, I think I may have already written I liked the 3 way brake unions because they came with a fixing hole and I could make them look a little more professional and a little like a PDWA valve, as I wrote above I had already 2 x 3/8 UNF 3 way brake unions purchased, only to find I needed 1 x 7/16 UNF 3 way brake unions, it was then I went for the original fixing point.

I had at first order a Moss PDWA rebuild kit, but before I went to Moss I did more research and found some people in he US had rebuilt them many times, so I thought for a car hardly ever used why bother with the PDWA.

I will add I advised my insurance broker about the change and he was very happy of why I did it and noted it on my file. I wonder how many of you have uprated your braking system and not advised your insurance company which you legally must.

Luke.

The reason I am aware of using a bleed nipple is because you can  buy a 5 way PDWA  from a Land Rover that can be made to fit a TR.  (599443 - I think.)  I sold many and merely blanked the 5 th outlet with a bleed nipple to make them suitable for TR, MG cars.

this is what they look like before fitting the bleed nipple to blank the 5th outlet.  Made of cast iron not brass.  They still cost the thick end of £100 from the Land Rover specialists.  Plus the bleed nipple of course.
