Fellas, I hope you can help.

My brakes stiffened up this weekend for no particular reason. The pedal is hard and takes a lot stepping to stop the vehicle. The master cylinder is new as of two months ago and the fluid level is ok.

Aside from leak near my exhaust manifold, all else is fine on the engine. Could this be a failure of the brake booster, or something else?

Thanks.

Make sure the booster is getting vacuum. Sometimes the steel fitting that attached the vacuum hose to the manifold gets clogged up.

Can I simply clean that with some copper wire and carb cleaner or should I be more careful. I don't want to screw up the plenum in the booster.

The fitting unscrews from the manifold. Take it out and look through it. If its already unblocked, the the booster problem lies elswhere. If its blocked, a wire or small gauge drill will clean it right out.
