200tdi with 300tdi axles

Hi Guys,

I'm planning on putting 300tdi axles on my 200tdi, as I wish to reduce the drive train back lash. I notice that my 200tdi has twin brake lines going to the caliper but the 300tdi axle has just a single line. Has anyone came accross this problem before, do you just change the caliper to the orriginal 200tdi or is there a trick with the brake lines? apreciate if anyone has the experience with this before. Thanks Jim

if your 200 has metric caliper bolts swap calipers
