1. No specific difference between a. no revs stationary steering wheel turn and b. 2000 revs steering turn - however there is initial sluggish resistance from steering wheel on both tests which wasn't there before, which lessens with more effort.
2. a. I turned the car slowly and applied brakes - slight steering resistance
b. I turned the car quickly and applied brakes - more steering resistance.
3. I did a weave at 60 mph and applied brakes - steering extremely heavy and difficult to turn - the more I applied brakes the heavier the steering got.
Hope this helps
The brake fluid reservoir is sat on a cylidrical piece of alloy metal with thin black metal pipes coming out of it. These pipes go off in various directions.
Behind the brake fluid reservoir is a fairly large circular metal thing about a foot across.
