D4 - a little bit of steering wheel wobble under brakes.

- 55,000km rear pads replaced at Ritter, rotors deemed fine and told front will be due at next service
- 62,000km approx developed severe wheel wobble at high speed under brakes, classic warped rotor signs so I had the font rotors replaced at my indy garage. Used DBA T2 4x4 Slotted rotors and Bremtec pad after reading thread on here. Braking performance is fine with these ad mayeb a little less dust than standard. Rotors also look good with black coating on hubs.

Hi Factory


I recently bought a 2010 D4 3.0 and it came with a slight brake shudder. Inspections by the dealer, and an independent, advised that the brakes were all good and well within tolerance.

Further research came up with the idea that the pads were indeed depositing stuff onto the rotors, and the cure was as simple as several very hard stops from 80-100kph.

After trying to put my wife and I through the windscreen a few times, the brakes now have considerably less shudder and I think a few more heavy stops should completely cure the problem

Worth trying first as it is a cheap fix!

Regards
Trevor

Thanks Trevor, interesting. When I was researching the topic, I cam across this THE REAL TRUTH ABOUT WARPED BRAKE ROTORS.. which supports what you are saying, I'll give it a try.

Slight shudder on mine when braking at speed on occasions,it’s definitely worn LCA bushes.

I just did rear rotors and pads and cleared up some wheel wobble.. Which is suprising as my lca are definitely due. Pads were genuine just approaching the sensor

I had the same shudder when braking (both at low and also high died), and also have the clunking sound when going over small bumps. I have a 2008 D3 Diesel.

Took the D3 to my local LR specialist here in Sydney, and got the front discs, pads and sensor replaced for $505. They also confirmed i need new LCA replaced.

They quoted me $1300 which includes the replacement of the sway bar bushes which they say should be done given they are working in that area anyway.

Thanks for reading.

Replaced both front arms today with Mehle HD (for those that don’t know, they use the solid rubber rear bush in place of the hydrabush, and not poly either).
New bolts with copper grease FWIW.

Brake wobble gone. Knocks and rattles also gone.

As I was having the odd brake squeak I also stripped the pads and cleaned the caliper/pad interfaces and re-lubed with brake lube. Also removed the stuck slide pins that were gummed up, cleaned and lubed.

Wheel alignment tomorrow.

Feedback on this thread, i managed to get my Disco out on to a quiet road and did several (maybe 8?) hard stops from 110 to 20kph in succession and has completely cured the brake shudder. Very happy. Interesting side point is after 4 or so stops there was some pretty good brake fade - obviously pushing Disco well outside design envelope. Brakes returned fine once cooled.

That's interesting. My indy has my 2016 SE at the moment, looking at a nasty noise coming from left front suspension on full right hand lock, but at the same time I've asked him to check noticeable vibration under brakes from high speed. New rotors and pads last year and new LCAs a few months ago, so unlikely to be that. Will do the high speed multiple stops when I get it back and see if that makes a difference.

Really interesting thread. Recently had new rotors and pads on the rear and pads in the front. I really had no issues but decided to try this ‘rebedding’ as an experiment. The difference in a car that has always had fantastic brakes is very noticeable. Thanks for the running the thread

Hi DiscoJeffster

Understand that the HD version is stronger, would this make the ride feel stiffer compared with hydrabush?
Thanks
