You're cruising on your SUV. All of a sudden, a squirrel appears in the middle of the road. And being the caring and rodent-loving person that you are, you immediately step on the brake pedal. However, your brake didn't seem to feel like its normal self. It felt like it took more effort from your part to activate it-it didn't feel like power brakes at all. Fortunately, the squirrel had a sense of urgency and jumped out of the way. The little guy is safe. You, on the other hand, won't be safe on the road for long if you don't do something about your brake.
What caused your power brake to malfunction? There are actually several possibilities. However, one of the leading causes of power brake failure in a diesel engine vehicle is a faulty diesel vacuum pump. It's most likely the reason for the squirrel's brush with death.
What's a Diesel Vacuum Pump?
As you perhaps gathered, the diesel vacuum pump is a component that's exclusively available on diesel engine vehicles. It's needed in such automobiles because diesel engine vehicles aren't equipped with a throttle butterfly that limits air flow, unlike gasoline engine vehicles. And a power brake system simply can't function without something that restricts air flow.
With those said, it's important that you get a replacement for a broken diesel vacuum pump as soon as possible. We'll give you a few pointers below on how to go about in shopping for a brand-new diesel vacuum pump.
Which Diesel Vacuum Pump to Get?
Replacing a diesel vacuum pump can be somewhat expensive. A new unit normally costs hundreds of dollars. Since you're going to spend a lot, make sure that you select an OEM diesel vacuum pump. An OEM replacement is generally of high quality, you can expect it to be both reliable and durable. You also shouldn't experience a lot of issues in installing it.
If you only need a new gasket or seal for your old diesel vacuum pump, then you can opt to purchase a diesel vacuum pump rebuild kit, which contains new gaskets and seals. It's much cheaper than buying an all-new diesel vacuum pump.
