Pete also said it's not a golf caliper, I thought it was from a mk4 golf

Interesting - perhaps your caliper is different from mine. Certainly my leaky caliper looked identical to those on the VW forum that Geoff’s link above leads to.

Going off-topic a bit in response to Scott, my nephew was not impressed when his VW-engined Skoda deposited its innards on the ground via the sump. Apparently that’s another TADTS. Serves him right for having bought a diesel. :twisted:

MOT is tomorrow.


they haven't, its an old wifes tale. Go on forums for mark V and mark VI GTIs, cambelts, timing chains, premature rust, brakes, etc etc etc , they sell overpriced junk to the uneducated masses .


They do have a reputation for reliability, but it goes back to the 70s (and before)! Was a Mk1 Golf a better car than an Allegro or Mk2 Escort? Definitely. Having owned quite a few VWs I'd say that the quality has dropped over the years, but also the quality from other manufacturers has improved. The build quality of my T5 is nothing like that of the T4 it replaced, but still much better than a Transit of the same age. We've had our Lupo for 10 years and 80k miles and apart from service items I've had to replace the alternator, indicator switch and the water pump.

MOT passed :D . Although he did remark that the RHS handbrake (the new one) wasn’t as good as the LHS one!

Bern,
You’re right that the reputation was probably earned when other manufacturers hadn’t pulled their socks up. But I still think that calipers shouldn’t leak after 6000 miles, certainly not regularly enough for internet forums to bitch about it. :?

You are quite right, the calipers shouldn't leak after 6,000 miles, that is very poor!

Congrats on the MOT pass. I'm waiting for the parts to rebuild one of my front calipers (original), after almost changing lanes unintentionally on the M5 on Monday when I applied the brakes - looks like the RHS front was sticking and getting hot, so when needed it didn't actually work!

So I will be on my 3rd one in about 7000 miles. This one is leaking from the handbrake seal. Peter is going to do me a special price on a new one and delivery is due Monday apparently.

That’s why I decided to go to Wilwoods. The originals just kept needing constant attention. Mind you, I never had a scary moment like you :shock: .

Rice crispie,
A new one sounds like a good idea. Good luck with this one, and I hope you get a good summer to try it out. I certainly plan to exercise mine as often as possible (Applecross, Mallaig & Skye are booked in 3 weeks time, then Ullapool and Scourie a couple of weeks after that).

The Bealach na Ba should be a good test for your brakes and/or leaky calipers John :lol: Watch out for the long drops though :shock:

And enjoy Mrs Fish's scallops and wild rice :smt023

Well, whoever it is must have been drinking something pretty powerful for it to have been that effective in clearing the road. A really neat job. Talisker? :lol:

More likely to be Laphroaig with that cleaning power, I would have thought :cry:

Been thinking of getting these for a while but slightly concerned as I agree VW build quality is not what it was.
My son had a 2000 m/y Mk 4 Golf and it was beautifully put together.
I also had a 2001 Audi A4 and that was probably the best built car I will ever own, 7 years and 50k miles of ownership later and I could see no real deterioration in interior or exterior at all. It was a mistake to part with it but it was 10 years old with 130k on the clock SHMBO wanted a change :(
After a flirtation with a Peter Shreyer designed Kia Sportage I went back to a 2014 Audi A4 Allroad,technically a better car but not the same quality build as the old one.
I now have a Q5, better, but not that undefinable bullet proof feeling I always had in the 18 year old A4

David,
If your originals still function well, keep them. I changed because I could no longer get the handbrake on mine to work well enough to pass the MOT, and I couldn’t get the replacement Dormans to work properly.
