Have you experienced along your way that your brake has made you so nervous?
Your brake pedal was so hard to press and yet your brake doesn’t grip the brake disk and your vehicle continues to advance.
Before anyone starts the journey at least he must have inspected the brake system, meaning the brake fluid level, the brake pads by testing how it grips the brake disks a day before the travel and I usually do this.
But one day I got so nervous that the brakes were not working normally. I assured myself that everything was fine because brake fluid was full, no brake fluid leaks, brake disks were fine. I went on to the whole journey with a very cautious driving thinking of what has been causing the problem.
Thankfully I got home safely. The following day I tried to look into the problem without any knowledge of how a power brake works. I know what a power brake vacuum booster is but I don’t understand why it is connected to the alternator.
As I look into the tube connected to the power brake booster and onto the alternator I noticed a certain part that joined the two, and it is this small thing below, called check-valve.
This is the power brake vacuum booster wherein the hose in the image below is attached.
This is the power brake vacuum booster hose connected to the alternator.
This is the alternator that charges the battery when the engine is running.
But it also helps in the brake system. The air produced by the alternator that passes through the hose and goes to the vacuum booster helps create pressure to push the brake piston when you press the brake pedal.
In between the alternator and the brake vacuum booster is the check-valve which is shown below.
This power brake check valve connects the power booster and alternator through a hose. In between the hoses, this check-valve is inserted.
On the images above the check valve is near the power booster but in my car, it is near the alternator. I noticed that this thing has been over the exhaust manifold and it was melted so it cannot function normally.
The video below illustrates the place of the check valve. Please watch.
The check-valve used here in this car model is simple, it looks not like a booster check valve. You can find different images and see what is used in your car because there are a lot. Check it here.
That made everything about brake system problematic which anyone cannot immediately determine.
It’s good I accidentally noticed it and I learned a lot and that learning is worth-sharing.
