Vibration under braking that isn't warped discs

Hi All

Just signed up as a member and I have no real idea about cars, other than how to get in and drive!!! My Range Rover has a persistent brake issue and it’s destroying the driving experience! It appears that taking it to a garage to diagnose isn’t solving the problem.

I bought a Range Rover sport about a year ago - my dream car!! And pretty much ever since I’ve had it, I’ve had a problem with the brakes.

Since buying, I’m now on my third set of discs and pads - I was getting vibration under braking and the garage I purchased it from said there wasn’t an issue after sending the car back twice!! I decided to get another opinion and the original garage had fitted the brake pads backwards (I’m told the pads are directional). The garage paid for me to have the brake pads and discs replaced at a specialist as I didn’t trust the garage I purchased the car from. The result was perfect driving, for a while......

After a few thousand miles, it happened again.... so, I decided to take it to a friend who I could trust, he is located 200 miles away and said my discs were warped. He advised that I might not have bedded the discs in correctly or had been sat on the brakes at lights after heavy braking. So, on go another set of discs and pads.....

Fast forward 3 months... and here we are, vibration under braking is back. Whilst I know very little about cars, I’ve been driving like miss daisy and new pads and discs every few months isn't normal - the vibration is the symptom and warped discs doesn't seem like the primary cause.

I’ve read that it could be corrosion between the hub and the disc or the hub not being cleaned properly before the disc is replaced. I’m hoping that one of the garages would not make this seemingly straight forward error, so was wondering if it could be something else.

I've read some threads on here where people have the same issue but I can't see what the solution was!!

The car is such a pleasure to drive when it works as it should, but it's horrible when it doesn’t! Please help!

Sticking callipers can over heat the discs and cause the warping there have been a few on here with the newer models.

Interesting snippet in one of the above articles,
are you running genuine or aftermarket wheels?

Make sure the hubs and wheels are corrosion free and spotless where they meet each other and flaky bits or rust can cause the disk's to warp when they are tightened up and give the effects of knackered disks
Then I read the thread and its already been sugested sorry

Bloke I know had very same with his jag , turned out the car had been in a bump and bent some important bits .
Never fixed it , just quickly part exed it .

Just because you've been having problems dont assume this is the same issue. As @brianp38dse said earlier, it could be a sticking caliper. Are there any other symptoms? Where are you feeling the vibration? Are any of your corners extremely hot when you get where you're going?
I'm sure those with more knowledge will be along with other suggestions.

Is the vibration coming through the pedal when you brake,
The steering wheel,
Through the body of the beast?
Have you had any mishaps with a curb at any point?
Standard or none standard wheels?
Recent tyres or puncture repairs?
Any offroading or grounding?
Any recent repair work to do with anything steering or powertrain?

does sound like a possible sticking caliper.

as a question which disc has been warping was there a diagnosis on which one ?

I think the op's has left the building!
