Why do I have to push hard on my brake pedal?
Vacuum – or really lack of vacuum pressure – is the most common cause of a hard brake pedal, and therefore the first thing to look at when a hard pedal is present. Any brake booster (whether from Master Power or any other supplier) needs a vacuum source to operate. When this happens, the pedal gets harder.

When did I replace the radiator sealant on my Subaru Legacy?
At about 230,000 miles I had to replace the sychros in the manual transmission. At around 250,000 miles I developed a radiator leak which was fixed with a bottle of radiator sealant. The car was finally done by a broken timing belt. If I had replaced the timing belt when my mechanic advised, the little Subaru would still be on the road.
