Warping discs............Again and again and again

I should firstly say that I know very little about Range Rovers, if this was my car, I would be looking very hard at the ABS system despite no codes showing. Can the system be turned off by removing a fuse for testing purposes or will that cause problems with the electronics?

I've not seen the brakes on this model but I would be thinking sliding pins or possibly some sort of obstruction in the brake pipe, possibly the flexi. It certainly doesn't sound right.
 
If as you says its all 4 wheel stations then you are going to need to look at where they all meet.

I trust the garage to carry out the checks; they are as baffled as I am!!

Servo upgrade - I have never had a recall on the vehicle; I assume JLR should have written to me if this was the case?.............

Car is at home, yes. Interested to see the wishbone check.....

Again though (and just to make prominent) the issue has occured from 13k miles so surely there shouldn't be wear on the majority of the parts?

hi

apologises not getting back to u sooner

put the suspension into normal ride height , grab the top of each tyre and rock them back and forth , see if there’s any movement , then try the same in access and off road height

indeed best to buy a cheap laser thermometer as can then check the discs after a run ,

here’s a link ref recall notices

https://car-recalls.co.uk/land-rover-uk-recalls-summary/

plse let us know how u get on and indeed when I get chance of the discs, callipers plse, thks

also assume they’ve changed all the brake fluid, fingers crossed gets resolved

just thought , think instead of shoes used for the EPB it uses the rear calliper

wonder if the faulty servo unit may cause this if it’s all four wheels, think it was where oil is allowed to pass the diaphragm

know when I had mine done they replaced the vacuum pump , servo, master cylinder along with the added pipework, plus changed the brake fluid to class 6

Also seen many replace the fronts with brembo which I think are around £500

think the freelander 2 also have the electronic rear callipers for the EPB, whereas , discovery 3/4 use shoes inside the rear discs for the EPB

Hasn't seen any maintenance in my D2 since it left the factory in 2000, yet still doing its thing today.
For me, electric brake calipers are right up there with automated manual gearboxes missing clutch pedals, any sort of electric valves or shunts on exhaust systems in the guise of emissions controls, timing belts within crankcases, electric driven water and oil pumps on engines, water-cooled alternators and auto transmissions going into neutral internally at stops ...... unnecessary innovations that cannot be mended on the side of the road WHEN they do fail.

Plus1 , also didn’t realise that some steering racks can be electric , indeed some of my pet gates are doing away with a physical engine dip stuck and the EPB, however if the EPB is checked every year it normally doesn’t give much trouble, half the issues are when there not adjusted correctly so when there applied the cable is too short therefore stripping the plastic gears inside the EPB module

think u can get the EPB plastic gears in metal now , alas haven’t got much knowledge regarding the rear callipers where they have an electric module attached to each one for the handbrake

also talking of daft designs recently saw a video where on the discovery 4 the engine oil lever sensor is inside the sump

don’t mind admitting some of these things put me off a newer landy , however we for some reason we put up with some of the daft designs , another example is on the TDV8 if the turbos fail, normally have to lift the body off

some of the myths on the D3 where some were saying if the rear fuel timing belt needed changing was a body off job , which isn’t true , watched mine being changed in less than 45 x mins , also seen pictures of someone replacing a turbo on a D3 without lifting the body off
 
I'd check the pads to see if they are all wearing evenly at the same rate side to side and also to make sure no pads are wearing at different rates across a particular pad face.
I work for braking supplier and 95% of the "warranty" claims we get for warped discs are nearly always down to DTV disc thickness variation. And it normally happens between 3 and 6k miles. Can be down to multiple factors, fitment errors, sticking pads and calipers, distorted caliper carriers, bearings, hubs, sliders. Start by checking the pad thicknesses with gauges and you may see a difference and be able to isolate which side at least.
 
But why though?.....
Is it that people find pulling on or stepping on a handbrake lever, opening a glove box by pulling on a tab, or adjusting their seats by lifting a lever are such chores that they need to be powered? I especially find the powered glovebox on Lincolns and other high-end vehicles dumb, because whiles it opens electrically at the press of a button, you have to reach over to manually shut it by hand.

Let's not even get started on push-to-start....:rolleyes:

The electric hand brake on a friends Citroen was automatic, as soon as the car came to a halt, the brake would apply. Touch the throttle to pull away and it would release, at least that was the theory. One day there was a frantic call from his missus, she was stuck in the outside lane at the traffic lights and the car wouldn't move as the brake would not release. Supposedly the ECU had failed, it was a very expensive experience getting the car recovered and fixed.:eek:
