Looking at putting VLT discs/calipers on my VB SL/E... any mods required? I haven't really sized it up but from memory they go straight on...

just something to be informed of

ive done the upgrade on my VL, but did the 1 inch master cylinder and v8 brake booster as well.

Upgrade to a rear DISC DIFF!! if u already havent got one.


I just rooted a rim by locking up quite easily in the wet due to a massive bias of vlt calipers on front and standard drums on the rear, and having a meeting with the curb.

Works wonders on the dry, but the wet is an issue!

but thats just from my experience, and sorry i wouldnt know if they will go straight on to a VB, prolly should thou

The front VLT/VN V8 discs/calipers will bolt straight on with no mods necessary. Even the pads are the same.

lad13s - your troubles are because you're using a disc rear master cylinder on an drum rear setup. They are not simply interchangable like that. The different master cylinders have different "break points" where brake bias starts being distributed differently to the front and rear. One is linear, one is not. I don't remember which is which, although autospeed did an article on this, and I think it is a free one.

I have put VN V8 dics/calipers on with everything else as stock with no problems.

The VL Turbo front brakes will bolt straight on (I suggest replacing wheel bearings!). If you have a disc brake rear use the turbo/V8 hydraulic setup, but if you retain the drum rear it's probably best to leave the master cylinder alone.

15" wheels are also needed.

Being an SL/E it already has rear discs, and 15 in wheels

He's right about the master cylinders there are different break points.

I have a VL Turbo master cylinder and booster so I doubt there will be an issue there ;)

My concern was mostly the boltup'ability... eg bolts line up etc
