RR Sport brake judder and wheel size question

[DaveRao]

I’ve got a Range Rover sport 2020 and had aftermarket larger wheels on it when I bought it in August from 20inch to 22inch.
I’m getting juddering when braking.
Sent it to Land Rover and they are saying that because the wheels have been changed to larger ones that’s caused the brake discs to wrap causing a judder when I brake.
Has anyone else had a similar problem?

I'm presuming you mean warp?

I can't see wheel size making a difference to brake warping, they sell them on 22s themselves with no difference to the brakes underneath.

I would put more money on some other fault causing the disks to warp.

Hi,yes warp sorry.
Well that’s what a thought about the size of wheels,but what could cause all fire discs to warp?

[camel_landy]

Lots of heat into the brakes (heavy braking, riding the brake with the left foot, etc...) followed by a period of being stationary, with your foot on the brake.

As the disc cools, it will cool unevenly and can cause warping.

Just a thought.
