We had a hard brake pedal in this Ford Fusion because there was no vacuum being supplied to the brake booster. After inspection, I found that the vacuum pump for the brake booster was not working. After removing the vacuum pump, found it broke off inside the camshaft and got metal all through the engine. Had to replace the engine on the Ford Fusion to fix the hard brake pedal and a new vacuum pump. it most cases this can be repaired if the engine did not have metal in it. That was not the case with this Ford Fusion. But nothing an engine won’t fix for a hard brake pedal. Good old quality ford product.

Hard Brake Pedal at Slow Speeds ” 2 Minutes Fix ” GMC Chevy
This video will be diagnosing an intermittent hard brake pedal on this Chevy Silverado. The hard or stiff brake pedal also applies to most GMC trucks. What we found is the brake booster was not receiving enough vacuum and on this Chevy truck the hard brake pedal was being caused because of the vacuum pump failing.
This GMC truck has an external vacuum pump that is belt driven to supply vacuum to the brake booster. A lot of the older trucks use engine vacuum to supply vacuum to the brake booster but on this truck that is not the case.
When the engine RPMs are brought up on the Chevy truck the brake pedal actually feels much better and that’s because the vacuum pump is spinning faster so it works more efficiently but at idle the brake pedal was very hard. We found that the vacuum pump had failed and will need to be replaced to fix the hard brake pedal in this truck.
