I'm helping my brother-in-law out on a problem he's having on a 99 LS400. The problem is that he basically is not getting any power brakes. The pedal is solid but has to be pressed really hard to stop the car. We checked pads today, which were good, and bled the system with no luck.
I started suspecting the brake booster and checked for vacuum and leaks. I can't see brake booster checkvalve so I'm wondering if it has one and whether or not it's even possible for the master cylinder to be suspect.
have the same problem?
