????????? Where? The only one i'm aware of (Sprint only) is attached to the N/S of the rear axle to protect the pipe to the N/S/R wheel cylinder from the exhaust which passes nearby, quite a hefty bit of steel welded to the axle, i've never seen THAT one removed or missing!

It's like a 4 inch long sleeve that clips over the brake pipe inside the engine bay by the exhaust down pipe.

What do you know, every day really is a school day! I've been working Triumphs since before the Sprint was launched and NEVER seen that one! Presumably on the pipe to the N/S/F flexi?

Yep,as you say on the nearside pipe in the engine bay near the exhaust manifold. Mine is actually plastic and clips over the pipe.
Re the solonoid heatsheild last time I looked there was one for sale on ebay.

The Heat shield over the brake line

#20 Post by Robert 352 »

I chuckled reading Steve’s comments about never spotting the heat shield on the left front brake line.

Steve, it’s the one shown on the right hand arrow!

I have never seen a Sprint without it!

I have arrowed the points where the other heat shield sits on the bulkhead. The first time the engine comes out of a Sprint which I am working on I drill the three pop rivets out and replace them with as you can see, some small bolts and nuts.

Then if you ever attempt to take the cylinder head off the engine whilst it is sitting in the engine bay you drop that back heat shield off, then undo the exhaust manifold bolts/nuts (whatever) and there is enough room to slide the exhaust downpipe down and out of the way.

The next time someone at the factory rewrites the Workshop manual or sends out an amendment they can add this comment. I suspect i will be waiting a while for that to happen.

Hi Robert, I know exactly why every NZ Sprint still has that shield and UK ones no longer do - SALT!

In the UK there is a flourishing industry (to which I contribute) making hard brake lines in materials less susceptible to corrosion than the original steel ones are. It's vanishingly rare to come across a Sprint still wearing it's original steel pipes, they've long since rotted away and been replaced. That's when the sheild disappears, into the bin with the old pipe. Because whilst that part of the pipe is in the engine bay and fairly protected, an inch or so away the pipe passes through the flitch and out into the wheel arch, where the tinworms can chew on it!

Nowadays, modern cars have plastic shrouded pipes hidden behind plastic shield plates, this doesn't entirely stop them rotting, just means an MOT tester can't SEE them so the rot goes un-noticed till something breaks! But back in the 70s and 80s cars in the UK left the factories with unprotected bare steel pipes, these often didn't survive our salt caked winter roads beyond the first MOT at 3 years old! Let alone the 40 years since!

Interesting to see what it looked like and where it was fitted though, i'd have expected it to be where the pipe crosses above the bigger shield on the bulkhead rather than on the flitch.

Having said all this, I did recomission a series 4 Sprint last year that had most of it's original steel pipes still present, a combination of low miles and a thorough Ziebart treatment being responsible for their survival. That car certainly didn't have the shield fitted, else I would have known about it! I replaced all the steel pipes with Kunifer regardless of their apparent sound condition (you can't always SEE the rot and this car had been standing many years, the pipes could have rusted internally from hygroscopically acquired water in the brake fluid) Futureproofing, if nothing else. I surely would have noticed the sheild, had it been there.
