[Dee911]

Hi all, my mot is, due in 3 weeks and I need to change the front and rear brake discs and pads. The problem is the front are 2 different sizes

front 266mm or 283mm
Rear one size 249mm?

Any help much appreciated.

Right I have brought rear discs but they didn't come with wheel bearings

Are these easy to install if I got them separately? And which ones will I need?

When I did the rear discs on my 12 plate DStyle 120 VTi, the front discs were the smaller size of the two sizes and on the rears the bearings were integrated into the discs.
On my newer 65 plate THP, the discs were larger and I had to phone my local dealership and give them the VIN in order to get the OEM part number for the pads, in the end.
