Looking to update the back brakes of the Ka following putting Fiesta ST brakes on the front. The car has ABS as it's a Streetka.

Fancy a disc conversion using Fiesta ST parts:

- Hub

- Discs

- Callipers and carriers

- Back plate

- Brake lines (was thinking HEL as they do custom ones)

My questions are:

- will the Fiesta ABS harness connect easily with the Ka's?

- with it having ABS do I need to bother with a valve to reduce the rear pressure or does the ABS compensate?

- which handbrake cable do I need to use?

Any advice would be appreciated.

hardcore mod! unfortunately I have no useful advice on this, other than I believe that the ABS connections are standard across the Ford range, and as long as the pressure is right without airlock in the ABS system to the rear, then the ABS would do the appropriate compensation so I do not believe a valve is required.

Cheers for that.
