Finally finished my own rear disc coversion !

Porsche brakes are nice but a bit OTT for most applications. Also I challenged myself to see if I could pull of this conversion myself ! And to produce it cheaper

Car:- 1973 Type 3 Fastback

Rear brake parts used:-

Type 3 Hubs (used)
Merc rear discs (used)
Mk4 Golf GTI Calipers (alloy ones) with pads and flexi pipes (brand new - bow available in plenty used).
Mk2 Golf flexi to rigid brake line brackets
Mk2 Golf GTI hand brake cables
Type 3 hand brake cables
Custom made caliper brackets

1. Type 3 hubs dia. turned down to fit into merc disc, redrilled and fitted with wheel studs to suit (i'm running 5x112mm PCD merc fitment wheels)

2. Custom brakets made to fit in place of existing rear backplate (i.e. between irs arm and bearing cover)

3. caliper fitted to bracket with Golf caliper carrier and bolts.

4. Mk2 Golf flexi to rigid brake line brackets sourced to secure pipes on top of irs arm.

5. Hybrid hand brake cable formed from shorted MK2 GTI outers and type 3 inners (drum end cut off and new nipple crimped on)

RESULT ?

After being a bit sceptical about the whole project (as in 'why did i ever start it' scenario ! ) It's turned out real good. All parts are good and servicable and should perform as OE. No road test has been done (parts have just been assembled)

The handbrake cable could do with being 1" longer as overall length was reduced because of cuttting off the type 3 end - may have new cables made up otherwise (as i found a local cable place that'll do anything ! BRILLIANT !!! )

I will post plenty of pics soon, I'll be dismantling the setup (only done one side for now!) to fully weld brackets.

Any questions/comments are welcome

Cheers,

Angelo

Excellent Angelo !

Would you be interested in submitting a tech article on the subject ?

Thanks,

Sandeep

Sure no problem !

Will pull together some text and pics.

Will let you know !

Angelo

hello.

job well done. i own a 67type3 squareback and want to convert all my drums into disc soon, but i do not have the parts needed, not the donor car. is there a bolt-on option available?

thanks.

Nice Angelo!
Especially since your set-up will save a lot of unsprung weigth also as opposed to the 944 set-up.

Well done that man.
Wonderful the feeling you get when it all works out in the end.
How's the pedal travel with the new rear hydraulics?

just in the process of final install.

mocked up one side, now the other is done and fully welded.

all painted and reay to go on, only prob I had was a little distortion on when welded, nufin a lump hammer couldn't solve !

Seems ok now, will fit proper and connect hydraulics.

Angelo

More pics to come soon!

That was the problem I had when I did the front link pin disc conversion on our '58 ghia.
I ended up getting my caliper mount milled square on all the faces.

Nice article Angelo.

I'm planning the same modification for my Fastback, using 411 rear hubs, New Beetle discs and calipers, and a custom caliper bracket...

Using MK4 Jetta steelies with the 5x100 PCD, so it would be directly compatible with my wheels:)
