Terrafirma TF638 front brake upgrade 340 mm – drilled/grooved discs / Performance pads

Front brake upgrade from 320 to 340 mm

TF638 combines Terrafirma cross-drilled and grooved 340 mm brake discs, Terrafirma Performance pads and new caliper brackets. The original calipers are retained. According to the supplier, this upgrade does not require brake bleeding because the calipers are reused.

Compatibility

The supplier lists Discovery 3, Discovery 4 and Range Rover Sport 2005–2013, with suitability conditional on existing 320 mm front brake discs. The detailed description specifically highlights most 2.7 TDV6 and 4.0 petrol Discovery 3 and Range Rover Sport 2005–2009 vehicles. Confirm the exact brake setup, especially for Discovery 4 and other variants.

This is the 340 mm kit. New calipers and the separate 360 mm upgrade are not included. Confirm wheel clearance for the chosen setup before ordering; the supplier does not clearly specify a separate minimum wheel size for TF638.
