Disc brakes
« on: June 16, 2017, 02:54:18 PM »
Hi all,.
Just wondering has anyone done Resteroid vh,vx , disc brake conversion yet..   I have vn disc all round and using vn master cylinder/booster set up.  Currently working quite well, but do feel a bit soft,  apparently this is typical of vn brakes.   So have been  on commodore web site  and standard upgrade is vt brakes, with a vs booster and vt master cyl combo.    I am going to use vy twin pot calipre's and disc's, with vy master cyl.   Looking at Resteroid write up didn't see anything about what brake master cylinder and booster he used.   
 So wondering if anyone had done the conversion and what booster/master cyl they used and how is it working. 
Thanks in advance.

Hi Shaginwagin

I'm using the the vt.vy disc set up with vt-vy master/booster but the oil reservoir is vs as the front is at an angle to fit under the bonnet

haven't had the van running yet to test

have a look in members rides (givin the van a tickle) also sammy has done a similar set up, I think Resto used the standared bedford master/ booster

hope this helps 
Phil

Hi Phill,
As I said already have vn brakes all round the foot brake pedal is Bedford with a combo of vn and Bedford mounting bracket under the dash.  Not hard to work out and managed to do it without any welding or cutting.   Most commodore owners tend to say vn brakes need upgrading.   Managed to get vy calipers, from a guy down the road wrecking his  vy,  just need to go back and pick up the disc's and master cyl.  Need them to make up pattern.  Already made calipres  for hq, then vn so shouldn't be too hard to make them for the vy brakes. 
Looking through Resteroid conversion he didn't mention what booster / master cyl he used so just wondering what other may have used.   Didn't think that bedford/hq booster master cyl would cope with twin pot vy vt calipre's.   On the commodore sites most seem to upgrade to vt brakes and use vs booster with slight mods and vt master cyl.
The good thing with vn is that it fits in under the bonnet, where if I change to vy it will need some alteration to get it to fit under the bonnet as it's about 80 mm longer.

go to members section, type in rogerfield and chechout his disc brake conversion, most impressive, i have fitted it to my 73 swb. lowered front end 1.5 inches and runs all commodore components so no trouble getting parts new or used, i am running stock bedford master cyl and power booster and pedal feel is light and stops fantastic.

Hi John,
Already running 15 commodore rims.  If beddie booster master cyl is working ok might just keep the vn set up as it's already by mod plated.

Hi Phill,
Had a look at you post, it's coming along nicely,. Not much longer now ?   Still got the top coat for the hz panel Van to finish then it's the Bedford, don't know how many times it's been pushed back.   Can you tell me how much did you machine off the front of the vn hub, ( where the wheel sits ),  and why?   Is it so that the wheel fits better. 
Julian

Cheers Julian I have been playing with the van a bit and need update the post but still got a fair bit to do,
I machined 3 mm off the face, this was so when you put the disc and rim on, the rim can locate it's self onto the hub

Thanks,  thought it might be that but better to ask to be sure.
