Reliant Disc brake conversion

[853tony]

any advice i got some of those brackets .but the caliper wont let the disc go far enough on to hub .
pads holding disc off . iam using mk4 golf  calipers on nova corsa disc is that ok . its for aspencade and will the brake be ok with the standard pot thanks . oh yes hi to all first post .

Take calipers off, fit disc, then mod the brackets to fit the calipers?

[tbone]

sounds like you hace the wrong discs.......Nova is what you want, Corsa ones are too thick

[Manky Monkey]

Didn't this come up fairly recently? Do the mark 4 caliper brackets have a step in them?

[tbone]

Now you mention it.... and you say your memory is bad 

The calipers are fine, its the carriers that have a dog leg, you have to use mk2 carriers regardless of caliper.

hi i sorted the mk4 are no good they have like you say dog leg . wether you have the nova disc or corsa disc still no good . i did  try to get some mk2 carriers but went down scrappy they aint got none they all on drums so i took 1 off a t reg passat estate and a 1 off audi a4 treg estate so i hope that helps anyone else out with same issuse thanks guys they must be straight carriers without dog leg in them

At least you've got it sorted Tony. We should draw up a proper list of just which bits fit.

hi i just completed my disc brake conversion, i used mk 3 golf calipers and carriers because the spring on the pads stops the calipers seizing and the nova discs but i had to turn down a step in the disc so it sits flat to the hub, the hubs were machined to suit the diameter of the disc hole centre, also my plates are 5mm thick (ebay!)but feel 6mm is better as the new pads in the calipers compress the rubbers a little creating a little pressure on the disc but should be ok.
The holes in the discs are about 13mm to mount on the hubs so upgraded the studs to M12 x1.5 pitch, i.e knock out the studs drill and tap m12 x1.5 and put a long stud in to suit my wheels with a nut behind and weld the nut to the stud. I used 70's slot mags so got the nuts and washers from graystons.. hope this helps steve....... one big lurnin curve..

A variation on the theme, but sounds like it will work fine Steve. At this rate drum braked Reliants are gonna become something of a rarity!

iv just gone to get the nova discs for the vw disc conversion and was told by the spotty herbert that there is a multitute of choice. someone told me to get 1988 1.6 solid discs which are 256mm but a supplier on e bay says all nova discs are 236mm. can someone give the definitive on which disc , year model ect and indeed the calipers and carriers i can use.

Hi dobber and welcome,the discs you need are nova 1.0 or 1.1 88 to 91,236mm.
try these http://cgi.ebay.co.uk/BRAKE-DISCS-FRONT-VAUXHALL-ASTRA-BELMONT-NOVA-KADETT-/250711685621?pt=U

Aye, welcome to Mankydom Dobber. 
Keep saying it -we ought to put together a definitive list of the parts for this so we can update the conversion article on the main website once we get it running again.
So.
Discs
Vauxhall Nova front. 1.0 or 1.1 litre, 1988 - 1991. 236mm diameter.
-thickness?

Calipers
VW Golf, mark 2, I used GTI. What years? Any other models that'll fit? I switched them over, left to right, cos it made routing the handbrake cables easier. Any other updates or suggestions?

Caliper carriers
VW Golf, mark 2?

Mounting plates
Anyone got a copy of the diagram we posted here earlier in the thread. After the Great Website Crash of 2010, we lost a lot of photos posted on the forum. A JPEG with all necessary measurements marked on it would be great if anyone out there can put one together. Also a selection of photos, showing the various stages of the conversion, from removing the original drums, to fitting the mounting plates, machining the hubs to suit the discs, fitting hubs, discs, carriers & calipers etc. Plus any hints or tips that would help newbies. Let's get this sorted once & for all!

cheers for that fellas, been keeping  photos as going along so will keep doing so till done conversion then send em in.

Yeah, that was the original magazine article I wrote a million years ago. Yoda, who originally set this site up on my behalf, accidentally copied a paragraph of text twice & I do think it might be easier to understand if we had photos of the axle on it's own, without being attched to the trike. A couple of pics of different trikes with the same conversion might help readers see how it could look on theirs too.
