Bleeding TLS axle brakes
DIR By: clunk

Yes I know, there are acres written about bleeding bleeding
difficulties with the later S3 axle. :banghead
Winstan the S1 has such an axle, 11" brakes twin leading shoe,
excellent stopping experience. I've been accumulating bits to
refurbish the brakes, Mintex all round, a couple of genuine
slaves for the rear axle, a decent S2 master cylinder
practically thrown at me by Albert Ross, who is indeed a
lovely bloke but not in :gay: that way.
Yesterday having a general clean up round the back plates in
preparation I noticed that the bleed valves, [on the front lower
cylinders] are so close to the bottom of the swivel housing that
it would be impossible even to fit a bleed tube onto them.
One of them has a rubber cap on it and there isn't even enough
space to ping that off.
I'm sure the backplates are fitted correctly with the cylinders
at 12 & 6 o'clock. The bleed screws seem to have quite a
lot of thread exposed, 5mm or more, perhaps they are too long ?
1. Would it be ok to rotate the back plates clockwise by one
hole to give access to the rear of the bottom cylinders ? [
long flexi tubes fitted because of the paras fitted]
2. Does anyone know the thread size of the bleed screw on S3s
as there appear to be a myriad of choices out there. ?
*help*

All tight at bottom / correct as you describe Dave, not sure
about (1) :-? or (2) sizeof bleed screw size.

it shouldn't really hurt to rotate the backplate as you suggest
, you'll still have pistons to apply the shoes along with
springs to pull them back off
i put 11" rear salisbury backplates on my 88" front axle and
this meant i had no choice but to set the slave cylinders at 11
and 1 o'clock respectively, they work just fine

Someone on here has replumbed the fronts so that the bleed
nipple is us the top. Im on my phone but a quick search should
find a pic. Flexi-copper -bottom cylinder- copper -top cylinder
with bleed nipple.

i've also done the replumbing on a TLS axle for a mate, really
easy and only minutes to bleed once done

Here ya go - done this on three vehicles now, and made a set up
for AlexB but I don't know if he used them:

Excellent, thank you. I've got a flaring tool somewhere.

I have just done this cheers Robin, the bottom bend it quite
tight I had to form it around a smallish screwdriver handle.

I too have converted to TLS fronts. I agree that space for both
the feed pipe and the bridge pipe is at a premium on the bottom
cylinder. I didn't tighten the cylinder into the backplate until
both tube nuts were successfully threaded in the ports. If doing
this again I would 'clock' the backplate-it would make buggerall
difference to brake efficiency and would make pipe bending much
less tight.
It is my experience that bleed nipples do come in varying
lengths-having a longer one in this application certainly
wouldn't help matters.

Thanks for all the wisdom and photos. :thumbs:
I shall probably now go both ways :haha:, re-pipe to bring the
bleed screw to the top after first clocking the back plate to
allow easier access and less tight bends.
After some in depth googling I am pretty confident that the
bleed screws are 3/8 unf.
I shall also probably look at Goodridge automatic bleed valves
as I am finding it increasingly difficult to get down and under
these days. I had these or something similar fitted to my
very first 109. They made bleeding a doddle, just unscrew
the valve a bit, give several long steady strokes on the pedal,
tighten the valve and wipe the jiz from the chassis/springs.
In these environmentally conscious days one would probably use a
bit of tube into a wine bottle to catch the waste dot4. At
about £9 a corner not too much of a strain on the pension
