Front Brake Upgrade Kit - 360mm. A front disc conversion for the front braking circuit, raising rotor diameter from the standard 320mm to 360mm.

This is the more comprehensive of the two front brake upgrade routes. Unlike the 340mm conversion the original calipers are not retained: the kit supplies replacement front calipers alongside the caliper mounting brackets, front brake discs and front brake pads. The increased braking radius and rotor thermal mass give a substantial gain in stopping power and in resistance to fade under repeated or heavily laden braking. Because the calipers are replaced the hydraulic circuit is opened, so the front brakes must be bled on completion.

Supplied with cross-drilled and grooved discs and a performance friction compound, which offers a higher coefficient of friction and greater fade resistance at elevated temperature than a standard road pad. The drillings and grooves vent gas and dust away from the pad face, helping keep bite consistent when hot or wet.

Wheel clearance: this kit must only be fitted to vehicles running 19" original alloy wheels, or 18" wheels with the appropriate spacers.

Frequently asked questions

What is the TF637 big brake kit?
The TF637 is a 360mm front big brake upgrade kit for the Discovery 3, Discovery 4 and Range Rover Sport L320 (2005-2009). It raises the front disc from 320mm to 360mm and supplies replacement front calipers, mounting brackets, Terrafirma CDG discs and Terrafirma performance pads.
How does this differ from the TF633 kit?
The TF637 pairs the 360mm Terrafirma CDG discs with Terrafirma performance pads, where the TF633 uses Ferodo pads. Both are the full 360mm conversion with replacement calipers for the Discovery 3, Discovery 4 and Range Rover Sport. Choose based on preferred pad brand.
What does the 360mm conversion improve?
Raising the front disc from 320mm to 360mm lengthens the braking radius and adds thermal mass, improving stopping power and fade resistance under heavy braking. The performance pads target consistent bite on the Discovery 3, Discovery 4 and Range Rover Sport front axle.
Which vehicles does it fit and any clearance note?
The TF637 fits the Discovery 3 (2005-2009), Discovery 4 (2010-2016) and Range Rover Sport L320 (2005-2009). A 360mm disc needs wheel clearance, so confirm your wheels clear the larger rotor before ordering.
