Having problems with your 2004 Jeep Grand Cherokee ?

Leaking brake fluid + Faulty cruise control

\015 Hi there, I have a 2006 Grand Cherokee with a brake fluid leakage from either the brake fluid container or master cylinder. I am hearing a hissing noise coming from behind the brake master cylinder when the engine is running, but can't be sure if this is where the leak is. Any tips?\015\012\015\012Also, the cruise control light blinks once when I activate the cruise control button, but nothing happens after that. If I press it again, the light would not even come on again.\015\012\015\012Thanks in advance for your advice.\015 Posted / edited by AnonymousUser on : 28-09-2020

Answers :

If you see fluid at the rear of the master where it attaches to the power booster then the cylinder itself is leaking. It's not often that the container leaks.
The hissing noise is very likely coming from the power booster. This must be replaced. If cruise has a vacuum hose that connects to hose to booster it's possible that vacuum loss at booster is causing the cruise problem.If you are going to do the booster, have a good tech take a look at it first. they are expensive and you don't want to change it on my advice alone...I'm not there and can't hear it!
