T32 big brakes upgrade: what’s needed?

[da_murphster]

you will need carriers on top of these

I would be tempted by the ebay kit to go with this - so you are getting known quality calipers and ebay for the rest:

VW TRANSPORTER T5 T6 340MM BIG BRAKE BIG BRAKE DISC CONVERSION CALIPER BRACKETS | eBay

2 X BRAKE CALIPERS (F0R 340MM). These can be used on any T5 / T6 front brakes to convert from standard 308mm, or 333mm Brakes to a 340mm Setup .

Probably getting on for £800 inc discs and pads
