Brake line leaking at front passenger’s side wheel

The brake line is leaking near the front passenger's side wheel. I had a catastrophic brake failure while driving. I heard a loud thudding noise and then I lost brake pressure. Pumping the brakes did not stop the car. The brake fluid was at the same level as when I checked the day before though. I noticed wet brake fluid around the front wheel on the passenger's side.
Experienced mechanics share their insights in answering this question :
Hi. Sounds to me that you have a leaking brake line to your brake caliper. Also the loss in brake pressure is because of the release in pressure from the leaking line. I would recommend having a certified mechanic come and inspect your brake leak in order to diagnose the problem and move forward with the correct repairs.

A: Brake fluid leaks are often caused by a worn seal in the master cylinder, caliper, or wheel cylinder. If you suspect your car is leaking brake fluid, call a tow truck to take your vehicle to a service provider for a brake fluid inspection. Brake fluid leaks can lead to total brake system failure.
It means that you have a brake fluid leak that needs to be addressed right away. If the vehicle has drum brakes on the rear you may have a wheel cylinder or brake line leaking. If the vehicle has disc brakes on the rear the caliper or brake hose may be leaking.
Leaks are usually due to issues with the master cylinder, ABS module, brake line, bleeder valve, rotor, drum, pistons, or general brake assemblies, so checking which component is above the leak can sometimes signify the source.
The only clear liquid to leak from your wheels is brake fluid, and that would make for a very dangerous situation. You can check the master cylinder inside of the engine compartment to check the level of your brake fluid. If it is low, then there is a strong chance your leak is break fluid.
If they`re near the front, left side of the car, it`s likely power steering fluid, according to Angie`s List. Check the power-steering reservoir and hoses to see if you notice cracks or leaks or if the fluid is low, recommends Cars.com.
It illuminates to show that the parking brake or emergency brake is engaged and must be released before driving. If it remains lit after the parking brake is released or if it turns on and off intermittently while you`re driving, it means you need to add brake fluid.
1. You should never drive with the parking brake on. Driving with your car parking brake on can do major damage to your braking system. It can wear down your brake pads quickly, as well as cause excessive heat in the system that can do other types of expensive damage.
The master cylinder usually has a plastic reservoir that holds the brake fluid, mounted with rubber grommets. The grommets allow for some movement caused by the pedal and fluid pressures. These grommets can leak brake fluid (a clear liquid) that can be seen with the naked eye.
Failed Brake Master Cylinder Seal: It`s exceptionally rare for brake fluid to leak from the brake master cylinder to the clutch pedal, but it is technically possible. The most likely cause in this instance would be a failed master cylinder seal.
What vehicle fluid has a blue or pink color? If you see blue or pink fluid at the front or rear of your car, it`s likely wiper fluid. While it`s not necessarily essential to how your car runs, it`s still important to have wiper fluid and working wipers. A leak means the reservoir is probably broken.
If you`re concerned that your axle seal might be leaking, here are a few things to look out for: Oil drops below your vehicle after it has been parked. If you start to notice oil drops on your driveway, it could be a sign of a leaking axle seal. Transmission starts slipping as you are driving on the highway.
Green fluid leaking almost always means antifreeze. Antifreeze leaks are one of the most common leaks when it comes to vehicles. Usually, the leak has come from a hose or clamp not attached properly. Antifreeze, or coolant, regulates the temperature in the engine, keeping it from overheating.
Red fluid: A leak that is pink or dark red in color is likely transmission fluid. This should smell odorless and originate near the middle or front of your car. If you confirm this as the source of the leak, check the transmission fluid levels and refill as needed.
Also known as e-brakes, hand brakes and parking brakes, emergency brakes are not powered by hydraulics and are independent of the service brakes used to slow and stop vehicles. There are state and federal laws requiring emergency brakes for motor vehicles [source: NHTSA].
Part of your vehicle`s brake system, the emergency brake operates independently of the main brake system to keep your vehicle from rolling away. Also known as a parking brake, hand brake and e-brake, the emergency brake was originally designed to be used if the vehicle`s main braking system would fail.
The emergency brake, or parking brake as it`s sometimes called, works independently from the brakes that you tap to stop your car. It`s that way on purpose so you have access to an alternative braking system should your primary brakes fail.
Answer: A parking brake, also called an emergency brake or e-brake, is a mechanical hand lever or foot-operated brake that is a backup braking system. It is located either between the front two seats or to the left of your gas and brake pedal.
Leakage may happen, however, from cracks in the O-rings or from a puncture in the brake line. Cracks can form if two types of brake fluid are mixed or if the brake fluid becomes contaminated with water, alcohol, antifreeze, or any number of other liquids.
Any leaks from the brake caliper will compromise the pressure sealing capacity of the braking system, which will not only make a mess of brake fluid but also significantly decrease its ability to stop the vehicle. You may notice a puddle beneath your car and the smell of burnt rubber from the leaking fluid.
If your foot slowly sinks to the floor with normal pressure on the brake pedal, the master cylinder is leaking internally. To diagnose a clutch master, clamp the rubber fluid line near the slave and press the clutch pedal. If the master cylinder is good, the pedal won`t move.
Faulty ABS Module

The ABS pump in the braking systems tends to carry some braking fluid. Some seals hold it in place, but if they get worn out, it can cause the fluid to start leaking out.

How long will brake lines generally last? Most new cars and trucks come with stainless steel brake lines that are expected to last seven to fifteen years before requiring replacement. It is one of the most durable parts of your vehicle and is considered a lifetime part.

Brake line leaking at front passenger’s side wheel
ANSWER : Hi. Sounds to me that you have a leaking brake line to your brake caliper. Also the loss in brake pressure is because of the release in pressure from the leaking line. I would recommend having a certified mechanic come and inspect your brake leak in order to diagnose the problem and move forward with the correct repairs.

What causes the passenger side wheel to wobble as if loose when braking?
ANSWER : It is possible that you may have a lug nut loose. However, if this were the case, the wheel would wobble at all speeds and not just when braking. This may be more likely related to a warped brake rotor. When the rotors get hot during operation and then cool down repeatedly, they can occasionally develop hot spots or low sports in them which create an uneven surface for the pads to press against when applying the brakes. When this happens, this can cause the shake or wobble feeling you describe. I would recommend having an expert from YourMechanic come to your home to diagnose the brake system and guide you through the proper repairs.

What is driver side front versus passenger side front? Isn’t an axle replacement the whole axle connecting the two front wheels?
ANSWER : Hi there. Wheel location is determined by imagining you are sitting in the driver seat. Your, and most vehicles today, have 2 axles in the front; certain vehicle still have a solid rear axle housing, but retain 2 individual axles as well. It sounds like you may have bent the strut, lower control arm, ball joint, and/or hub when you hit the curb. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a suspension inspection.

abs light on brake line broke have been replace I bleed brake line but brake pad still go to the floor now wheels lock up
ANSWER : Hello. If the brake pedal is going to the floor then that means that it is not building pressure. If the brake system has been fully bled and there is no air in it then most of the time it is a bad master cylinder or it can be caused by a bad ABS module. If the brake fluid was low and if air got into the system then the only way to properly bleed it is with a scan tool that would allow you to open and close the valves in the ABS unit. Air gets trapped in these easily if the brake fluid gets low. This can also explain why the brakes are locking up. I would usually use my scan tool to bleed the system out first before going any further. I would also scan the brake control module to see what it is reading as a fault. If there is no air in the system and if there is no prominent code then I would replace the master cylinder first. If you want to check out why your brakes are locking up, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

What parts would I need to fix brake fluid leaking from my front front inside wheel?
ANSWER : Hello, thank you for writing in. While replacing the brake pads and rotors is standard service after they wear down, they would not cause a fluid leak. You likely have two separate brake system issues happening at the same time. The hydraulic brake fluid leak is the cause of the pedal hitting the floor. Without the ability to build hydraulice pressure and control the brake calipers, the brakes do not work. To find what needs to be replaced, you have to find where the fluid is leaking from. From there you can replace the line, valve, or other part which has failed. After the repair is made, you need to bleed the brakes and replace pads or calipers need be.

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.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Strong knocking from front driver’s side and passenger side when making turns left OR right.
ANSWER : The steering rack and pinion assembly is mounted in rubber bushings; they may be deteriorated and allowing the rack and pinion to contact the sub frame making the knocking noise.

The other component to look at is the struts upper bearing and rubber bushing. These get dry of lubricant and should be lubed with a teflon grease when installed so the rubber will not get damaged.

Have someone feel the top of the strut mount under the hood while the steering is turned back and forth to see if the knocking or popping is in the strut. The rack and pinion bushings should be inspected from under the vehicle.

If either or both are bad then they will need to be replaced.

A mobile mechanic, such as one from YourMechanic, can come to your home or business to inspect the knocking noise at your home or business.
