I have a problem with the brakes in a P38 4.6. 2000.
When driving, once in a few brakings, the brake pedal is very, very hard and hard to press, so it's hard to brake.
When driving, sometimes you can hear something like "trtrtrtrtr" near the brake pedal.
There are no errors on the dashboard. The lights are not flashing. There are no errors in the nanocom. There are no leaks.
For the test, I took out the black ABS relay. Of course, the errors appeared, but the brake worked normally for a long time (a dozen or so brakings), so I think the high-pressure tank is tight.
Any ideas where to start?
