Swooshing noise when braking

The car is making a loud swooshing noise, especially when I apply the brakes. I think it is the rotors, brakes, or something associated with the brake system.
Experienced mechanics share their insights in answering this question :
Brake noises are pretty common. Worn pads can make a rotational scraping noise while driving if the wear indicators are contacting the rotors. The noise will most likely be worse while braking. Performing a visual inspection of your braking system is the only way to know exactly what your Honda needs. I recommend enlisting a certified mechanic to perform this inspection and make the repairs needed to get you back on the road.

A leak of air from the master cylinder gasket into the brake booster. A missing or damaged foam silencer. Many vehicles that have brake boosters come with a piece of foam that blocks the hissing sound. If the foam is missing or damaged, you may hear the hissing sound.
The loud metallic noise when braking that you will hear means that the brake pads have been completely worn down. The growling or grinding noise is being caused by the friction of the two pieces of metal (the caliper and the disc) rubbing together. This can scratch or “score” the rotors, making the surface uneven.
Hissing. A hissing noise is usually the brake booster leaking air. There could be a leak in the vacuum line, the booster diaphragm, or the master cylinder. A small leak could cause a hissing sound when you press on the brake pedal or let off.
This refers to the uneven wear of brake discs and is the result of rotor run out. If your brake discs are unevenly worn the brake pads come in contact with the flat spots present in the rotor`s surface which causes the vibration that we call brake shudder.
If your brakes emit a sharp grinding sound while braking, it`s likely that the brake disc and the caliper are rubbing together. The sound is usually heard when you stop your car, but you may also feel the brake pedal rumble as you step on it.
The metal-on-metal grinding noise you hear is the steel part of the brake pad grinding against the brake rotor, and it`s not good. You need to get a brake pad replacement immediate when they are shot before they also destroy your rotors or brake calipers, which can be a very expensive repair.
Excessive pulsation of the brakes can be a safety concern especially during slippery road conditions. The reason why your brake is pulsating is that that brake calipers are unable to grab hold of the rotor. This can cause a slipping or sliding predicament.

EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.

Low brake pedal and anti-lock brakes are not kicking in.
ANSWER : The brake pedal is working to stop the vehicle, but there may be air in the controller unit causing the ABS brakes to not function. I recommend bleeding the brake system from the farthest location from the master cylinder to the master cylinder including the ABS unit. If the brakes are still spongy after a full bleed, then the controller will need to be replaced. If you need further assistance with your brake pedal being spongy, then seek out a professional, such as one from Your Mechanic, to help you.
