Replaced the vacuum pump about a week ago. Brakes have never been so good. It also cured a stalling issue I've had with the car since purchase. Such an inexpensive part for so much gain.
Haven't used yet. I had intended buying this a few days before I did, when I eventually got around go it, it had doubled in price. I was desperate so I payed the price. Would never do it again, I would rather do without.
