i recently boughta car and i was told it need a brake booster
I use to have this same problem when i didn't eat meat, and that's where a lot of your iron comes from, (it comes from other things like some veggies but meat is thee main source) and it is bad to have low iron levels, it slows down your energy and all that good stuff, so just eat meat or some veggies like spinach and broccoli hope i helped :)
You really need to get some iron in your blood. I'd just take the pills.
In most all automotive applications, the brake booster is a vacuum actuated system, located directly behind the Master Brake Cylinder, it looks like a big, metal doughnut. It can easily be replaced, using only common hand tools.
A mechanical device which attaches to the brake system to multiply the force the driver applies with his foot (or hand as in the case of a motorcycle). The device uses air, vacuum, or hydraulic fluid to accomplish this purpose.
