Hi there – from your symptoms, there is still air in the brake system. Newer cars, with ABS systems integrated, are more difficult to purge air from without pressure bleeders and actually exercising the ABS pump. I recommend a brake system flush performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, and clear up your brake issues.

Air in the brake line(s) is the most common cause of a soft/spongy brake pedal. If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft. If the brakes are soft or spongy, this is a good time to change or flush the brake fluid.
At a basic level, cars like your Jeep use what are called “friction” brakes. These brakes use the contact between two types of material to bring the car to a halt. A friction brake may be either a disc brake or a drum brake.
Faulty brake rotors are the main culprit when a car, truck, or SUV shakes when braking. Ideally, brake rotors work with your brake pads to stop your wheels from spinning. But as rotors get older, they get thinner from wear and tear, and they can become damaged.
And as a sign that Wrangler`s war years are behind it, dual air bags are standard, anti-lock brakes an option.
The ABS modulator is the hydraulic assembly in vehicles that use the anti-lock braking system (ABS) to optimize the brake pressure. A damaged modulator may lead to malfunctioning of the brake valve resulting in spongy brakes.
The most common reason for a soft brake pedal is simply air still in the system. The easiest way to diagnose this problem is to pump the brake pedal gently a few times. In doing so, the pedal should become firmer with each gentle press of the pedal. If it does, then the necessary answer is bleeding the brakes.
Most present-day Jeep braking systems run off a hydraulic fluid system. In basic terms, when you push the brake pedal an arm pushes a piston into the master cylinder. The piston`s function is to compress the hydraulic braking fluid and create pressure in the brake lines, which are connected to the brake calipers.
Ceramic brake pads have excellent stopping power and disperse heat well. Ideal for most normal driving applications, they produce very little dust or noise and are long lasting. Many foreign and domestic vehicles are equipped with ceramic brake pad formulations from the factory.
The Jeep death wobble is a mechanical defect in your Jeep vehicle. The death wobble is caused by loose, damaged, or misaligned parts in your Jeep`s suspension or steering system. Due to the mechanical defect in your car, the parts can shake loudly or violently when you travel at high rates of speed or on rough terrain.
Brake pads that are worn, damaged, or warped, may cause vibrations along with a squeaking sound that indicates brake pads require replacement. Similarly, brake pads that are soiled from dirt, oil, or other toxins can cause vibrations as they attempt to grasp the rotor.
Jeep Wrangler YJs were manufactured between 1987-1995, Jeep Wrangler TJ`s were manufactured between 1997-2006, and Jeep Wrangler JKs were manufactured from 2007 to present.
Jeep® Wrangler helps protect you and your companions with safety and security features including advanced multistage front airbags, body-on-frame construction, an on-road/off-road four-wheel disc Antilock Brake System (ABS), Brake Assist and more.
Spongy brakes are common and dangerous problems for any vehicle and indicative of a deeper problem. Most importantly, a soft or spongy brake prevents you from stopping as quickly as you need. Spongy brakes could be a sign of a leak, and a small leak can turn into a large one with just a push of the brakes.
This can be due to a number of problems: a leak in a brake line, a loss of pressure within the master cylinder itself due to a failed seal, or air being introduced into the braking system. Your first reaction to encountering spongy brakes should be to rapidly pump the brake pedal with your foot.
A brake pedal that is functioning optimally should feel firm, as if it has a tight hold on the brakes. A “soft,” or “spongy,” brake pedal describes a situation when the brake pedal does not have that firmness.
If the ABS light is present in your Jeep, it is important to have it checked as soon as possible, this is because an ABS fault can lead to issues with braking performance, and could eventually result in an accident.
comes on when a problem is detected with your Jeep`s anti-lock brake system (ABS). Anti-lock brakes are an important safety component of a vehicle, and in a sudden or emergency stop, they prevent the vehicle`s wheels from locking up and causing skidding or loss of control.
Note: The Jeep Wrangler has been equipped with two types of drum brake: the 10-inch drum brake and the 9-inch drum brake.
What is Brake Plus™? Brake Plus is a rear-end collision deterrent system, which means it can help give distracted drivers a cushion to reduce the likelihood of a collision.
This is important to know if you are replacing your brakes yourself and need to buy the right parts. Are front or rear brakes more important? The front brakes are more important and you should pay more attention to your front brake pads and rotors, while definitely not neglecting your rear brakes.
Through countless hours of research, our review team found that the best type of car brakes are ceramic. Ceramic brake pads disperse heat well, have excellent stopping power, and are ideal for application on your daily driver.
Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.
In many cases, the cause of death wobble is a loose or poorly fitting track bar bolt. In this case, tightening or replacing the bolt may correct the issue. (A track bar bolt needs to be extremely tight!)
1) Your pedal vibrated because the ABS (anti-lock braking system) was activated. If the pedal vibrations (pulsing and groaning noises, too) happened when you e-braked, chances are ABS was activated. ABS prevents your tyres from locking up, which could lead to an uncontrollable skid.
