It was a 1985 Daimler Ds420.
So if I spray contact cleaner into the solenoid, and it just cleans it, will it stick again

I know an electric wizard is best to ask. Likes a Daimler too

Normal recommendation is contact cleaner to get rid of the dirt then some graphite powder in there for lubrication.
For most things I think WD40 is fine but I wouldn't use it for the steering lock unless it was an emergency and I had nothing else.
Dry moly spray is the best stuff I find for lubricating stuff like that.
It can be a bit messy so go easy with it! (molykote is a name of one but others are available)

I got rid of a car with a distributor on it last August.
Will a contact cleaner keep the solenoid thingy lubricated?

Servisol Contact Cleaner & Lubricant.

Just ordered some servisol, thank you

Took the old girl out for a run today. Gearbox was really smooth then after a few miles I felt a thumping from the front. Made an unpleasant shudder when braking.
Got it home, offside front brake was smoking.
Laser temp gauge showed the near side brake disc at 68 degrees c.
The offside disc was a toasty 312 degrees c.
So, discs and pads on order. Seems a seized caliper and warped disc has been causing me some issues. Question now is, do I bite the bullet and get a new caliper or can the old one be unstuck and made workable

Hmmm, if it sticks and causes a fire?
I would replace it for a rebuilt or new. That's my penny

You could get a 2nd hand one, new OE are silly money. Heard Britpart ones work okay but have a square edge to them so be careful with balancing weights on the wheels. Should be fine with standard wheels/tyres.

On a P38 I would replace the calliper, they are as cheap as chips, expensive on the newer stuff though. Are you sure it's not just the slider pins seized?

Plus 1 on slider pins.

Another vote for checking the slider pins

- IMHO Sliding calipers are the work of the devil

Myblackt5 · Jan 4, 2020

I had cleaned and greased the slider pins before I took it out for a spin. The piston was a bit of a struggle to move but it seemed to free off .
It took a little while for the problem to appear. I'm going to whip it all off in a bit and see how bad it all is.

You can refurbish the caliper pistons if not too corroded.

Myblackt5 · Jan 4, 2020

I was thinking about that but I've never stripped a caliper.

RangeRoller dt · Jan 4, 2020

Hardest part is bleeding system after. Is a dirty job though but very rewarding

There are videos on YouTube. Nothing special about it. Getting the pistons out can sometimes be fun. Think some do that part in situ.

Workable and reliably so ?

Maybe, when were they last serviced ?

Is the disc pooped also ?

Myblackt5 · Jan 4, 2020

I have ordered a set of discs, I think the seized caliper has caused a warped disc. When it all gets hot it can be felt through the brake pedal.

Disco1BFG · Jan 4, 2020

IMHO, get the calipers refurbed with stainless steel pistons ( and new genuine seals ) - they are done for life then - I don't use anything else now - it simply isn't worth it.

Myblackt5 · Jan 14, 2020

I've done a bit of work over the weekend. Used the recommended electrical contact cleaner on the steering column. So far all seems well.
New caliper, caliper carrier, discs and pads, changed the brake fluid.
Went out for a lengthy test drive and for a brief moment, all is right in the world.
Thank you all for your help and advice, it has been invaluable. And saved me a lot of money.
