Hi All - I've looked through the archives and have not seen much on this
topic.
Finally time to get moving on my conversion to disc brakes on the TR2.
I have 2 front suspension assemblies that were ruthlessly cut from a TR3
and also have a distribution 5 way tee fitting with the the long standoff
and brake switch and all mating fittings.
I will retain the lockheed master cylineder - but hope to just fit new
pipes with lockheed on one side and girling on the other to adapt.
Do you have any words of wisdom - i.e did you have to add any brackets or
make any other special provision?
Also - could use some detail pics of TR3's with disc brakes - especially
where the flex hoses terminate and where the 5 way junction mounts.
As an update -- Bill Lynn of VTR got me my Build record on the TR2 and the
engine number matches my title number - things are looking up - I'm not
making any modifications until I get the title but preparation continues.
As an aside - the front suspension assembiles that I got were terribly
rusted and caked with dirt and who knows what else - They were on the earth
in a barn for many years - I've been squirting them with penetrating oil
every day for the last few days. . I gave them a quick sandblast to remove
dirt and gunk and took the impact wrench and hammer to the ball and tie rod
joints. A few hefty blows with the BFH and all the tie/ball joints came
apart neatly. - The bleed screws and hoses came off each caliper (the tr3
version without external piping) but I broke the bolts that hold the pads
in place.
All that done - time to see what I had - I spent about 5 mins and blasted
each caliper a bit more - especially around the pistons - Yuck - just a
toothy rusted mess - I filled each with aero-kroil - again 30 year old
gallon can from years ago. and let them sit for while - hopeful that they
were not leaking around the pistons. After a few hours, I went to work -
nothing - clamps did not move them - hammers and chisels - I decided to try
the grease gun approach - I took one of the grease fittings from the
discarded trunnions and took one of the hydraulic hoses and mated them
together with by shortening the fitting and tapping with 5/16 tap similar
to the threads on the trunnion - put it all together and..... it leaked.
Plumber solder and flux and got a good seal. It worked great - I saw one
move and clamped it down until the other moved - then just pumped until
each was out as far as possible - I could see clean chorme on the pistons!
Now to spend a few hours picking the rubber and rust out of the calipers
for the dust seal - that part of the caliper is really quite rusted but
most of the groove is still intact.
Anyone tried the BPNW pistons - they have some kind of plating that sounds
cool - and do you know if they work on the TR3 calipers?
Thanks,
Chris
