My 330mm brake conversion - all on!
« on: January 22, 2012, 04:25:19 pm »
I have started on my BBK - I dont want to tread on the toes of Dave the brake Guru - I just fancy having a go at things myself.

These are the basis of the conversion so far - Mercedes 330x28 drilled. They have an overall height of 46.5mm. They are very reasonably priced - although they are not coated so I will be having to prepare the areas that the pad wont work against to keep them looking nice.

I have offered up a template of a 996 pad and they seem to cover the friction area perfectly - the pad just meets with the machined area on the inside, so I shouldn't have a rusty strip.







Took them to my local machine shop and they are going to take out the centre bore a bit more - then make a spigot to fill back in again to the 65mm dia. of the VW hub.

Will be a while till I can afford calipers but atleast I can make a start on the discs. Think I will drop them in this week for machining.

Cheers

Discs are now back from machining - we took the centres out in diameter then made up some stainless spigots. They fit a treat!





Time to paint them now and hunt for some calipers!

Thanks all for the kind comments

Discs are painted so will put some pics up soon, and I have sorted a pair of 996 fronts that need a refurb for decent money so that is good for me as I like to tinker!

will soon be time to get the machine shop to do me some carriers! :party:

do you have a pattern for the caliper carrier or did you just make your own measurements?

im considering a BBK but finding the brackets etc is putting me off.

I've been struggling on replies for carriers etc too but then I came across this site http://www.porschecalipers.co.uk/uk/index.html

I emailed the bloke who really seems to know his stuff so if you need any bits for doing a BBQ hes very helpful and not badly priced either, he'll have stock of the 312 brackets in the next week or so, and he does brackets for larger sizes too.

@ Viken;  I dont have a pattern but the machine shop I use are very good and said they could make me some up from scratch if I just take the hub/disc/caliper along to them. Or I may draw one up on CAD if I get the time.

I have the experience and resources to have a go at this but I would reiterate that if you are unsure about any of it then employ the services of a chap like DaveB to sort you out....you dont get 2 chances where brakes are concerned!

Full marks Jim....

And full marks again for realising these are brakes and need a good coat of looking at.

I've got a drawing for that carrier if you need it, all the carriers you,see on eBay and other sites are direct copies of mine that I've supplied over the years, it got to the stage where I wouldn't supply to anybody with a Leicester postcode.

Thomas's site has come on a lot, he was a member over on uk-mkivs and I've supplied him some stuff in the past we were forever bidding on the same stuff on the bay!

You'll need a healthy wheel spacer for that setup but that said there a massive sense of achievement for running something you've put together yourself, built not bought springs to mind.

I even considered having some discs commissioned at one point, hydraulically there no benefit in running these over the NQSBBK except a little thicker disc and a slightly larger pad little bit heavier too....aren't they...!

if you need any help at all pal give me a ring, gonna pm you my mobi over now.

if anybody is struggling getting hold of me please keep trying, I get like 40pms a day, say 3 mins a pm to think and reply that's two hours a night on top of my day job and actually getting the stuff made!

Website goes live very soon tou'll all be pleased to hear you'll be able to buy online

DAVEB1970, sent you a couple of PM's. i know you must get loads! :happy2:

just wanted a price for the brackets, bolts and hoses or everything required to fit the boxster calipers


also do you have any calipers to sell already refurbed and painted?

if not how much would it be to refurb/service calipers i buy from a breakers etc?

cheers
