One critical component of your car may go unnoticed since it is tucked away in the back of your mind. Until it’s too late, many people don’t know it exists!
Hydraulic brakes are what you see here in your car. The fluid in your Jeep’s hydraulic brakes has to be checked and maintained just like any other element of the car.
By regularly inspecting and repairing the hydraulic brakes on your vehicle, you can help keep everyone in it safe. A faulty braking system might lead to an increased chance of an accident if the brake fluid isn’t changed.
Here’s all you need to know about changing and adding brake fluid to your vehicle!
What Type of Brake Fluid Does a Jeep Wrangler Take?
There are several types of brake fluid available, but you want to ensure you obtain the one specified by Jeep.
Jeep recommends the use of DOT 3 or possibly DOT 4 Brake Fluid for its wrangler.
Most automobiles and trucks now on the road are equipped with DOT 3. In contrast, the reduced viscosity of DOT 4 fluid makes it a preferred choice for anti-lock braking systems and traction control.

Jeep Wrangler Brake Fluid Leak Problems
Having a leak in your braking fluid might be dangerous. In most cases, it is caused by a difficulty with the seals, the hoses, the master cylinder, and a number of other things.
When disc brakes wear down, the master cylinder’s brake fluid level might fluctuate somewhat. You’ll have a more fluid-filled system with less pressure on the piston. This isn’t a leak, but it’s worth mentioning because it may look to be one.
Brake fluid might leak from your Wrangler’s system for a variety of reasons. You’ll find them listed here.
1. The Bleeder Valve
Your Wrangler may have disc brakes on all four wheels, or it may have drum brakes on the back. Using bleeder valves, air may be released from the brake lines in any type of brake.
Braking fluid might leak out of the brake system if these valves are broken or removed.
2. The Brake Disc
The master cylinder and all four brakes are linked via brake lines. Rubber and steel can be used to make them. Rubber ones, in particular, have the potential to collapse.
3. Piston seal
Brake caliper pistons seal the disc brake caliper pistons to the disc. When the brakes are applied, the piston seal prevents brake fluid from leaking out of the caliper. Time will take its toll on this seal.
One of the most typical areas for leaks to occur in a Wrangler that has been parked for a lengthy period of time is the radiator.
4. Cylinder on the wheel.
It is in this way that the wheel cylinder of drum brakes takes use of the braking fluid pressure when the brakes are applied. If you have drum brakes on your Wrangler, this is a typical problem area.
Observe the rear wheels, and you may notice that one of them has a splatter of brake fluid on it (on the back part). That suggests that the wheel cylinder is faulty.
5. Reservoirs for Fluids
A fluid reservoir is attached to your master cylinder. It’s a reservoir for additional braking fluid. The plastic in many of them can break and spill braking fluid.
How Often Do You Need to Change Brake Fluids?
Having your brakes and brake fluid checked by your mechanic at each oil change is a good rule of thumb to follow. They’ll be able to provide you with the most accurate information on the condition of your brakes and whether or not they need to be replaced. Brake fluid should be replaced every four to five years for most drivers.
How Do You Add Brake Fluid in A Jeep Wrangler?
Is this your first time behind the wheel? Changing a flat tire, replacing a U joint, or using a tire repair kit may not be at the top of your list of skills, but you have to start somewhere. As a result, I’ll be demonstrating how to add brake fluid to a vehicle today.
1. Make Sure Your Vehicle Has the Correct Fuel Supply
As previously said, it is critical to purchase the suitable refill. The suggested kind for your vehicle can be found in the owner’s handbook or on the trunk lid.
You don’t want to make a mistake like putting the wrong gas in your vehicle.
2. You Should Park Your Vehicle on A Level Surface
To get a clear view, your car should be positioned on a level surface. A sloping parking lot might create inaccurate readings since the liquid level is greater on one side than the other.
It’s a good idea to read the owner’s handbook first if your car has anti-lock brakes (ABS).
3. Open the Hood with Caution
To obtain a true image, park on flat ground. If it’s parked on a slope, the liquid level may be greater on one side. If your car has ABS, check the owner’s handbook first since you may need to depress the pedal.
4. Remove the Cap and Dry It Well
Before you open the tank, cover the fender. When opening a new liquid bottle, it’s best to avoid wearing expensive clothing to avoid damaging it as well as your car’s paint.
Be sure to wash your hands properly after coming into contact with the liquid, since the liquid itself has the potential to be hazardous to your skin if not washed off.
5. Check the Fluid Level and The Color of The Fluid
Before opening the lid, clean it with an old towel or cloth to prevent dirt from falling into the tank. If this happens, the liquid’s color will alter and eventually deteriorate, causing brake system damage. It’s best if you clean it fully before.
Plastic tanks in most new automobiles are clear, and the MAX/MIN markings are clearly apparent. You’ll be alright as long as you don’t exceed the MIN threshold in the amount of liquid.
If the liquid level is below the MIN mark and the color is clean and free of dirt specks, it’s time to refill.
6. Refill Time
It is recommended that you only fill it up to the MAX mark. As a result, there is no need to overfill it, as this might result in damage. For refilling, you may require a tiny funnel.
7. Drive A Car Through a Series of Tests
You’ll want to make sure the interior of the cap is clean before putting it back on. Once it’s in position, make sure it’s securely sealed by pressing it down until it falls into place.
A test drive is now in order to make sure everything is working as it should after all the hard work. Once you’ve returned, double-check the tank for leaks and make sure everything is installed correctly.
