Hi there!

i have issues with my brakes. Have a gs300h 2015 and had vibration when i press on the brakes, i can only feel it on the pedals. Took the car to lexus and they changed the disc and the pads spent aroo £400. Then after 2 weeks it came back again. So took it back to lexus and they said it was just dust accumulation on the hub. 

A bit worried that there’s other problems. My warranty just ended.

It's not unusual for new disks to warp.

I had three new sets on my old Saab before I got a set that worked and my BMW went back after a month too.

I changed the Lexus ones myself a couple of years ago, they're OK but not perfect but the disks came mail order so swapping them would be a pain.

The brake dust accumulation is a valid response. I had a similar problem on mine. Apparently the pads and discs are only lightly used on a hybrid as most of the braking is done by the generators. Therefore it is possible for dust to gather as it is not often rubbed off during heavy braking. What I do is to have a couple of hard brakings from about 70mph when safe to do so and this seems to have solved the problem.

I'd second what Alan said. I get all sorts of rumblings and vibrations because I avoid using the brakes wherever possible, but a good hard stop (or two) is always enough to cure it. My Prius was pretty much the same, so when it comes to regen brakes I think it might be a case of "they all do that, sir."

If the Lexus dealership are now correctly claiming it's brake dust, are they going to refund you the £400 for unnecessary disks and pads?

Thanks for the replies!

i have to speak to them about that because the brake disc they changed was still good. But they said 30000+ miles is reasonable mileage for the disc to cease. But as ive said i checked it before taking it to them. Should i ask for refund?

I'm on nearly 60000 on my GS and apart from some surface rust the discs and pads seem barely worn.

mine too. I think that 30,000 is too low and they should not ordinarily have needed to be changed. Some Dealers of all marques are looking for revenue.

I think it's worth pursuing. They misdiagnosed the problem and replaced the disks and pads unnecessarily.

30,000 miles might be reasonable for a car without regen braking, but for a Toyota/Lexus hybrid it's nonsense. My wife's Auris hybrid did 80,000 on one set of disks and pads and my Prius would have done similar if I'd kept it long enough. The GS is heavier so it might not get quite that far, but as Alan and John have already suggested, 60k is easily achievable.

On my previous GS disc gave up at 90k miles.
