I took mine apart to clean and rebuild to find out your not supposed to split them

Er.... Why not ? - I've split loads of them to get new SS pistons in ( and normally new seals ... ) there's a square section O ring seal between the two halves which is easy to replace .....IIRC, said seal comes with the full OEM seal kit too ;)

Now I've seen them at 30 odd each if be mad not to buy.

Or, possibly mad to buy - there was a thread on here a while ago about the complete lack of quality in certain "aftermarket" brake calipers .... ( they were carp :eek: )

It's a debatable topic. Both rave and the odd tech man will tell you you can't split them due to the amount of heat that runs through them causing a change in the surface. I didn't really understand this - the mating surfaces remain the same - you aren't replacing anything apart from seals and pistons. The calipers are torqued together. Surely if one surface changes shape so slightly both do?

It was my fault that I split them to be honest - I cracked one of the bolts when on car not thinking

ive rebuilt hundreds if not more as long as use good seals theres no issue with splitting calipers, we used to get the halves re-plated so they looked like new with new bolts and pistons fitted
 
And this is why this forum is so useful as you have saved me 50 odd quid. I've rebuilt a few calipers but they've never been splittable so I took rave as gospel. I'll order the kits.

My calipers are in a bucket of vinegar and petrol and have been for some time so shouldn't be too bad.
 
Oh and it's bull**** that the o ring is in the set if your not to split lol

Agreed - though I've just searched paddocks site, and they only do the piston seals now o_O :rolleyes: ..... matters not as square section nitrile rings are available elsewhere :)

According to the image lr direct do a seal kit with the o rings just minus the pistons lol. I don't know if the pistons are reusable or not yet. I know stainless is a good idea but I might be able to clean mine up. I'm not on a really tight budget but I'm putting a pot aside for my floor and rear cross member which is going to be best part of 500 quid

SS pistons are deffo worth the money IMHO - they really should last more or less forever.... I've done all the pistons ( and seals ), on both our D1's ( which got tedious as I wasn't getting paid for doing it :rolleyes: ) - but they won't need doing again..... ;) ....

I understand budgets though.... can only spend it once :( :eek:

I'll buy ss if worthwhile. You got any pics of your two? I like your ethos of running two simple cars as everyday motors. How long hsve you been running 2 d1s? I have an a5 for my commuting and business miles and love it but there's still a part of me that would like to not have that kind of financial commitment. I guess it's part of the job though as it's my work tool really. Under warranty now but will nag my head or cost me when I lose that warranty or extend it. Everything's so complicated now isn't it. A 300tdi is never going to cost thousands to repair. If box goes it's an eBay job and a weekend. I don't even have a dipstick on my a5
 
SS deffo worthwhile - paddocks do em cheapish...

My D1 is in my avatar - have had for 4 years now, since the ni$$an POS PU fell in half :rolleyes: no real issues, welding yes, but the repairs I have done should easily last 25 years...

We'd actually had a new L322 after my original D1 - but in the 8 months we "paid the finance" (!), it was here driveable for about six weeks, so that went back and we bought the PU - both were a complete waste of money - and I still kick myself for this. ni$$an "customer service" didn't give a flying feck :mad:

SWMBO's Pug died shortly after the POS PU - wiring loom went - £1400 for the loom, then fitting, and an ECU and fitting ( and the vodka and tonic ), and the main stealer didn't even know if such crazy expenditure would fix it.... so we didn't - we found her a D1 too.. so we've both had D1's for more or less the same amount of time ......

I've said this before - I genuinely will never have a modern vehicle again - they are crap. I have a colleague who has had a new Merc every 3 or so years - even he has lost patience - he's not buying another co they are, in his experience, crap :rolleyes:

I'll find some piccies ;)

Probably the biggest reason why I wanted a van as part of my package at work, it's all on them and I just drive it, when the Disco is welded up again we're getting shot of the eurobox 206 and we'll be a 1 car family again :)

Exactly what I used to do mate. I had a hilux which I loved and was a tax dodge. I then moved firms and took a lesser truck which broke my skinny body. I decided I wasn't doing 4 hours a day uncomfortable so got a Merc. Merc was absolute junk and never again. I traded in for my a5. My a5 is chalk n cheese with the Merc and I really do love it. I get allowance instead of cc and fuel card which does eat in to my own money but I get a nice motor out of it. I just hate how complicated everything is and wouldn't touch it myself. There are ecus and management systems for everything. The gearbox is insanely sharp and it's a joy to drive. However, it does come at a cost which will no doubt be the depreciation. It was a hard call and still is. Right now, with so much mileage I feel I did the right thing but I might change in for another hilux in auto guise when paid off.

My heads a mess with cars. Part of me just wants a d1 or fender to keep forever and use for all my mileage (prob 30 odd k) but my last contract stated I had to have a car less the 5 or 6 yo so o bought me a nice one. I love it. I think if this is this good how good is an s5 etc. The other side of my brain thinks I could have gone and bought the best tdi disco or fender I could find and keep it forever. Maintainence costs would just be parts and my time.
The reason I dig into this is because it may cause my project go take a different route. I was thinking camper based but I'm now thinking as good as I can make for a daily and give it a chance to do the mileage. No clause in my new contract re age of car.
 
To me, given the complexity of modern sh*t, and their rather well known proclivities for breaking expensively ... SWMBO and I made the decision to spend the money on tools and facilities. It's not ideal *, but living high in the pennines, the modern stuff just can't take the damp :rolleyes: ( genuinely how frigging pathetic is that :mad::mad::mad: - it was even mentioned in the FFRR saga :confused: )

(* = largely because if I/we don't do the work, then it does not get done - I do not trust "garages" to treat an old vehicle with any respect - I actually asked the local indi to quote me to do the clutch on SWMBO's D1 - there answer was - "it's not worth it - it'll be as rotten as a pear, they all are, so better to scrap and buy something more modern" - I have no words for this attitude :mad::mad::mad: - and it is perhaps as well I only asked out of interest ... it'll never, ever, EVER, get a new clutch anyway :p.... Complete auto box is here, ready to roll :p :p )

I reckon motor vehicle engineering reached its peak in about 2000 - anything more modern is full of crap like electric handbrakes and other such nonsense.

I notice that age of car is an issue with some breakdown/recovery cover - and it certainly is an issue with insurance. Notwithstanding that insurance is a scam in just about every sense :rolleyes: , if you run an older vehicle, you have to read any prospective policy quite a few times and make damn sure it'll do what you want - or rather that the contract is enforceable in court, as required. IMHO agreed value is a must.

I could go on, but you get the idea. ;)

I both agree and disagree. I definitely agree that we have a throw away culture. Some people just don't get why I am doing my d1 to such an extent.
I do think gearboxes within the last 5 years have become an incredible milestone on engineering. Drive a new c63 with intent and it's impossible not to be impressed or smile. I guess it depends where your heart lies. I love a spit and sawdust motor that can be stripped at home. I love the fact that it's not throw away and all parts are available and I could essentially build a new old car. However, I also love new German stuff. I'm blown away by it but that's also because I like a fast car too. Do I need a fast car? No, not in the slightest but I do love getting a wiggle on through the country with a flappy paddle box! One thing is never have again though is a modern 4 pot German oil burner. A landy is supposed to sound rough. A Merc isn't!!!

I'm heavily influenced by our experience of a certain FFRR ;) - a "loss" of £8K over such a short period with no apparent upside made it an expensive lesson IMHO. Thus, far easier for me to avoid any chance of a repeat by steering well clear. Dealership support was also less than ideal too :rolleyes:

I do think that the engineering within modern stuff is very good - and I have a pal with Ferrari's, Audi A8's and even a Lambo of some description - all fine tools, just not reliable enough for us.... Of course we could move to a better climate .... and maybe one day we might ;)
 
You hear far more of timing chain tensioner failure now and the high pressure fuel pumps nowadays also produce horror stories. Everything is built to such tight tolerances!

I was investigating the BMW M62 4.4ltr V8 as a potential donor engine for a project and I thought I would find out what breaks and what I should look to get done before it was fitted, timing chains and VANOS were key trouble spots and when investigating why I found that the chains run on plastic guides FFS not even idler rollers/sprockets, even the valley where the chain runs through 90 degrees is a plastic guide FFS.
