|
|
Now that the truck's finished I've taken a pretty well sorted 15/50 from a friend to give me something to do over the winter
It may not look that good but it's a one owner 25K car which runs very sweet. I drove it 4 miles from Ken's place to mine.
I have a first question about the 15/50 rear cylinders - how do they work? I can see the piston that the handbrake controls but can't see how the hydraulics make this move without spitting out fluid - or if there is a small piston in the top of the cylinder then how do you access and replace any rubbers in this?

where are the ancillary bits for the handbrake ?
the simple movement of the cylinder in the backplate take up the handbrake .the internal piston operate the movement in the same way.

Thanks Ray,
On a closer look - and after a good scrub of the internals - I can see that there is another piston below the handbrake piston. After a lot of effort to free the piston it's all very pitted so I think I'll be safer getting new ones.
The cost difference between a full repair kit for all 4 corners and new cylinders isn't very big. |

Dalbuie,
I always get my old cylinders resleeved with stainless steel liners. This is a popular option in Australia and it's no dearer than buying new cylinders, but will last just about forever.
It's also a good idea if your classic is only used on irregular outings and stands parked for long periods, to use silicone brake fluid in the system. It is vital that your hydraulic pipework be thoroughly cleaned out and new rubbers fitted to all your cylinders before it is put in.
The usual glycol based brake fluid is extremely hydroscopic, meaning it will absorb water. Up to 10%. With heavy braking, the fluid gets hot and causes this water to boil in the lines. This is what we know as brake fade.
Brake retailers will tell you all the dreadful things about silicone brake fluid (none of which have ever caused me any problems) mainly because your brake hydraulics will last forever and they will have no work. Silicone rejects water. Once the system is sealed, no water can enter and there is no corrosion or pitting in the steel components. Therefore there is nothing to tear and wear the rubber pistons.
I put silicone fluid in my A40 back in the 1990's and it's still in there and the brake hydraulics have never needed touching! Obviously brake shoes still wear out!!!
A very serious consideration if you are contemplating a brake renewal.

Many thanks Penman but I've managed to pick up a 15/50 manual which has been a help.
I've found a supplier for the cylinders and it appears that the rears are the same as the TR2 and the fronts the same as the Morris Minor. Wish there was a site somewhere that listed all the compatible parts between cars

Hi Rick, I've not been as 'into' it as the truck given the other projects on the go just now (http://www.nostalgia-cars.co.uk/) but I do have all 4 corners stripped and the new brakes on order so will start to fit these next week. After that I can get the petrol tank refitted - no idea why it was removed - and at least I can drive it in and out of the garage depending on weather etc. It's mainly just a fix up and sell job over the winter to bring in some cash for something more interesting (another truck perhaps ) |
