Bentley Turbo R making whining noise when turning right and
Discussion
I have only just bought the car two weeks ago, it is a 1993 Turbo R with 76k miles.
When I turn right, the car makes a whining noise. Also when I brake, the car makes the same noise. It only does it when the car is hot, and gets gradually worse the warmer the car gets until it reaches it’s maximum ‘whine’.
The mechanic tightened the front bearings and had a look at the rear. They are all apparently okay. He claimed that the rear bearings cannot be tightened but said they looked fine.
I have just returned home from a 20 minute drive and after about 7 minutes, checked the brake fluid and both levels appear to be fine.
The brake pads have been re greased. They are fairly new having only been changed 700 miles ago, and to eliminate any chance of this problem being brake related, the mechanic swapped the pads over from one side to the other.
I understand that it is possible that it is a rear bearing and my mechanic hasn’t checked it sufficiently. Although surely this wouldn’t make a difference as to whether the car is hot or not?
Might it be the pump failing?
Any advice from experienced Bentley and RR owners much appreciated.

Caliper sticking?
Drive car as you did & at end of journey carefully check if wheel on the noisy side is hotter to touch than the other 3.
Got same issue on my Range Rover & similar symptoms.
Another clue is brake dust on the wheel, is there more on the noisy side than the non noisy?
Not sure if your mech is fluent in Bentley! But some knowledge of them is always invaluable ime.

Thanks for the suggestion on the Calliper. I will look into it.
An update:
I've just taken the car on a drive (night time with much less traffic and need for braking) and found that the noise is less offensive. However it is still there when I go around a bend at between 20mph and 50mph (cannot go faster than 50mph as I live on a small island!). Similarly, the noise is worse if I have had just been using the brakes heavily, even if I turn right and do not press the brake pedal at all. It is very strange.
I've checked the brake fluid once more after taking it on a good run, and the levels seem good. The invoices from the last owner show that it was serviced only 700 miles ago.
Any more tips I could share with the mechanic would be highly appreciated.
