Rear brake line routing

[tr7dan]

!980 TR7 DHC RHD

Does anyone have a clear picture or diagram of the routing of the rear brake line in the engine bay where it exits the pressure balancing valve to where it disappears under the transmission tunnel as it would have been from new ?

Thanks

Sorry only have LHD cars. But I think the routing in the transmission tunnel is the same for LHD and RHD cars.
But as far as I know only the routing across the front bulk head is different ...

Thanks Beans

Mine's RHD so I guess where the pipe comes from under the trans tunnel and turns right in your first pic, mine would turn left and then ? maybe run under the servo and across to the pressure valve ? Is the hole I've marked with a red arrow for a brake pipe clip ? and also, do you know what the two studs are that I've marked in blue ?

It's a long time since I took it to bits and clearly, I didn't take enough pictures, mind you, all the reference pics I have are prints from negatives - no digital cameras or phones when I took this to peices

It's the first and only one I've worked on and I'm just trying to make sure I have everything in place before I refit the engine and box so I don't tie myself in knots !

Mounting points for the coil on early cars. Not used on later cars, but the studs were never deleted from production.
At least they provide a nice mounting point for a big inline fuel filter!

Very jealous of your pristine engine bays Dan & Beans.

Is the steering column bush a poly one Dan?

Well in my case it hasn't seen much action since it's respray

In my case it is. I have been using these (Superpro) for well over 15 years now.
So far they have performed very well.

Agreed Beans.

In the case of the steering bush, I found that it needs a good application of silicone grease each year to prevent stiction against the steering shaft for prolonged driving in summer temperatures.

This is the brake pipe routing in my FHC if that helps

It's the one that was on the car when it was built - it's been off the road for thirty years so hasn't had much use.

If it’s the original factory nylon item I would look at replacing it whilst it’s easy to access from both sides.

The original items fall apart after about 30 years as did mine, leaving a wobbly steering column.

Perfect - exactly what I needed to see, thanks for that.

Cheers, will look into that - did I read somewhere that they are a complete ar$e to fit.... ?

On a cold day in a complete engine bay, it’s an absolute pig.

With an empty engine bay and a poly bush that’s been sitting in a mug of boiling water, it’s much easier.

There are many posts in the Forum about this over the years if you search them.

I can’t remember if I pulled the steering shaft back through the bulkhead or not to make room. Under the dashboard, I vaguely remember undoing the clamp on the steering shaft to slide the lower half towards the drivers seat.

Do the steering bush now when the engine bay is empty, it is SO much easier!

On routing brake lines, when I fitted a stronger diff with LSD & discs to the 8, I fitted a distribution block to which the rubber hose goes near the diff centre, with individual pipes to each wheel. I found this so much easier & quicker to bleed that I then fitted the same to the 7. Eliminating the cross diff pipe has made it much easier to get a good high pedal at the first bleeding.
