Mercedes W114 250 Coupe - help!

Free at last! Liberal use of my rubber hammer and lo, the disc is off. Chatting to our lovely Postlady (her pride and joy is a VW splitty) about needing new calipers, she mentioned her 5 year old Jeep had just needed a new set, so thought mine had done quite well at 46 years old.

She delivered the replacement membrane for the compressor - ordered Thursday pm from Germany, while the replacement pressure gauge from Ludlow, ordered same time, arrived Friday am. How cool is that?

Perishing wind on an otherwise pleasant day. Tony popped over to view the caliper (BER), brake disc (he showed me how to clean it up with an angle grinder with sanding disc but grooves in the surface were beyond MB spec so new front and rear ones ordered) as were rear drop links, an ultrasonic cleaner and a zinc plating kit.

My other neighbour Dan, who lost his wife to cancer a month ago, also popped in to see how it was coming on and looked forward to me getting the blaster going so he could do some stuff.
 
Are you keeping the standard size front discs and calipers?
 
JJJ - yes.

Graeme - noted, fortunately the disc pads went long ago! Mask will be on.
 
Front caliper off, all straightforward until attempting to remove the brake hose. Impossible to remove the hose connected to the caliper as the suspension got in the way and the hose itself was being twisted so it was re-connecting itself. The nut holding the hose connection to the brake pipe was impossible to get at because of the shape of the bracket and the hose got in the way of any socket from below. I ended up sacrificing the brake hose at which point no problem but getting the connector off the brake pipe is going to be left to the experts, I am not going to get close to a fragile bit of brake pipe.

Front calipers were also beyond repair. So a set ordered from the same supplier. An expensive day.

Could you not have spun the detached caliper around the hose to free it?
If the hoses and pipes are as originally fitted, chances are quite a few will need replacing.
Hoses collapse internally and brake fluid being hygroscopic may have pulled moisture into the steel lines.
 
I tried everything - the combination of disc and suspension location plus length of hose made spinning it impossible (it's a big lump as well).

If the brake lines need doing they'll be done but they all look very good - I suspect they have been replaced at some point.

Ah - down right bloody awkward. I know what you mean by 'big lump'. I have a beyond serviceable W123 rear caliper kicking around the garage floor that is nothing but a nuisance. Keep meaning to get rid of it but by rights a lump of iron that big should be recycled but I suspect my local council won't take kindly to me depositing in the recycling bin meant for thin cans.

That, is a boost if they have been replaced. Tony's work?
 
I shall ask him. He did all the bushes and a lot of suspension work, plus new fuel lines so brakes could be on the list. It is clear that in areas where the predominant texture is crusty and the colour rusty, the brake lines (though not looking new) are entirely free of any of those features.
 
Were the brake pipes you have disconnected dry of fluid? If so, then possibly new pipes and adding fluid and bleeding deferred to nearer recommissioning time.

Hopefully, the translation arrives some time tomorrow. For the mere three pages there are, I suspect there will be some very useful info re installing the V8. Talking of which - do you have it at home with you? Is it steel or alloy sumped?
 
Rear ones had small amount of fluid, front ones no.

The V8 is in the S class up in Bedford - I intend it to go direct to workshop as it lacks an MOT and I have (usual story) no space on my drive at all. So no idea on sump.
 
The Potters Wheel.

Here is the W114 equivalent of the "Potter's Wheel" intermission. Sorry about the sound track!

I recognise a lot of the weak points there, fortunately mine has had the majority done, apart from a few small places. I wonder what they charge?

On the subject of charges, of the eye-watering nature, I asked D class for a quote to do the seats. They were pretty much twice the cost of having KHM do them (and they are not cheap), so Germany it will be.
 
Music by Klaus Doldinger I think grober....
 
Apart from my ultrasonic cleaner anabasis I did little on the car today other than a bit of sanding, cleaning up of seat bases, finishing the rustproofing of the bumper strengtheners and puzzled over the front disc brake. Having tried the correct procedure yesterday with the caliper, it took me some time to find a link to how to remove the disc, which I don't necessarily fully comprehend (and I lack the necessary impact tool). Rather than get bored and hit it with a sledgehammer, I decided to potter around and think about it instead, in the vain hope that I could do a rapid lunge at it with a rubber hammer when it was lulled into complacency but no such luck.

Probably off to Germany next week to pick up parts, drop off seats at KHM and save enough to make the trip worthwhile.
