Hello again! This is the time of year where I get back to resolving issues instead of wandering about in the camper
Got a very scary behavior the other day while backing out of a tight spot in a public land boondocking site here in Quebec. So going in reverse, very very slow, in a slight incline to the rear, so I had my foot on the brake pedal all the time and was just ever so slightly pushing on and off the brake, repeatedly. At some point, I needed to stop faster and when I pressed down on the brake, it became REALLY hard and was only able to get to a slowwwww stop. Scary.
I have to say that in regular driving, my brakes work just fine.
Read up a bit on the forum and test the vacuum booster and master cylinder. With the engine off, after a few pumps, the pedal becomes hard, and then doesn't go down with sustained pressure. If I keep my foot on the pedal and then start the engine, it then goes down as vacuum builds up.
So I decided to give it a try in normal driving forward. At around 50mph, if I pump the pedal a good 3-4 times, on the 4th press of the pedal, it becomes really stiff again and in no way possible I could do a quick stop.
Can any of you report this as being normal?
Thanks for your always helpfull insight
