I saw the thread recently on the VT brake upgrade and was wondering why my VS brakes are better than my VL V8 brakes? Can I put a VS brake booster in my VL for instant better brakes?

Im pretty sure the good old VLT calipers but the VL V8 has cross drilled rotors and doesnt stop anything like the VS.

VS, VLT and VL V8 are all the same calipers. It's not the calipers that make the improvement, but the brake booster (VS) and master cylinder (VT) combination.

Thats what im trying to say, if I put a VS booster and VT master cylinder on a VL it should give the stock calipers more bite, can you use VT calipers on VL discs?

Yes, it would probably improve the braking. No, you can't use VT calipers on VL discs. You're require VT hub adaptors fit VT discs to your stub axles. Available on eBay for around $250 a apair. As seen here: Some original photos have not been recovered yet.

You can get 16s over VT brakes. They were issued from factory with 16" steelies. Think it was about $3.50? It's not bad for the budget stiff, should try it. Some original photos have not been recovered yet.

Lol, garlic bread caught my attention too. When funds allow, I'm looking at doing the VS booster/VT master upgrade, or the full VT kit if I can afford it. from what I've read it should make a fair difference in braking, I'll be looking at the VT front brake kit at some stage also.

Geex, just clears the strut brace! Should get yourself a V8 spec one, it sits up closer to the firewall.

Yes, standard VL bearings.

FYI - The VS booster is plastic and a single diaphragm unlike the VT booster which is a metal body and a twin diaphragm. - When fitting a VT master cylinder to a VS booster it is best to fit a spacer between the booster and master for clearance than to cut the actual pushrod.

I put the booster kit from Matt at Race Brakes Sydney on my VL, and it was the biggest improvement I have made to brake pedal feel.
