For those of you that have a Jeep Liberty, the time will come when you need to replace the radiator as with all vehicles on the road today. Most radiators have plastic tanks on them, which makes repairing them very difficult. It is sometimes better to just replace the entire radiator then try to fix it.
Watch the video below to get the basics on this procedure.
I know there is a lot I left out but I will be updating it soon so stay tuned and remember that all radiators are not the same so get an OEM for the best fit and performance.

Well lets start with the basics before we learn how to fix them. Your brake system is made up of many components. The very basic brake system uses a brake booster that is attached to a master cylinder. The master cylinder feeds ( hydraulic fluid ) brake fluid through a combovalve that feeds the rear wheel cylinders ( Drum Brakes ) while another set of lines off of the combo valve feeds the calipers ( Disc Brakes ) in the front.
Most cars and light truck have a front disc brake system installed into them. The rears as they are called are either drum design or rotors as well. You can look through the rim to find out what you have.
Disc Brake systems contain at least three parts. The Rotor or disc as it is sometimes called. The caliper assembly which is what you have to remove to get to the brake pads, and of course the brake pads themselves. The hydraulic system that most brake systems use can be a little complicated ,so watch the video to understand it better.
The Brake pedal is directly connected to the master cylinder via a push rod the travels through the fire wall. Pedal pulsation is caused by warped rotors. A soft or ” Spongy ” pedal can mean to much air in the brake lines and a pedal that drops slowly when you are holding down the brake pedal can mean leaking seals in the master cylinder.
The Master cylinder has a reservoir on top of it that holds the brake fluid. You can check it by looking at the side of it and seeing where the fluid line is at . You should keep it between the Min and Max level. If the fluid level drops down to low then a sensor on the reservoir will send a message to you on the dash
You may even see one of these depending on make and model.
As far as repairing your own disc brakes, I have created a short list of things you can do yourself to make the process a little easier.
First is Safety. Always support your vehicle the proper way and use something to block the wheels so the car cannot move. Jack stands are a must and make sure they are placed in the right position under the vehicle.
Remove the front tires to gain access to the brake system. Never use just a scissor jack to hold up a vehicle if you plan on getting under it.
Next remove the caliper bracket from the steering knuckle. Then remove the caliper assembly from the caliper bracket.
On some cars you can simply remove one bolt from the caliper assembly and swing the caliper up to gain access to the brake pads.
Once you have access to the rotors, pull them off and inspect them for signs of wear like ,cracking, bluingscoring or high ridges at the edges. You can have them resurfaced at most brake shops and even at some parts houses.If your rotors are to thin, you may have to replace them. Remember to always replace in pairs.
If new rotors are to be used. invest in some brake clean to remove the shipping oil on your new rotors.
Next you will have to push then brake piston back into the caliper. You can use a C clamp or even a large pair of channel locks. Use one of the old brake pads to act as a backing for the spreader tool.
If you plan on doing this a lot then invest in a good spreader tool. You’ll be glad you did. The make several and most can be found at your local parts house.
After you install the rotors onto the hub the simply put everything back on they way you removed it. You should consult with an after market repair manual for the torquing specs. That is very important. Haynes and Chilton make some good ones and can found almost anywhere. Even your public Library has them.
The last thing you should do is bleed the system. This can done a lot faster if there are two people doing it. Have one person behind the wheel with the engine running while the other person opens and closes the bleeder valve. Make sure your friend does not lift his foot up while you open the valve . Air will be pulled into the system and you will have to start the process again. Always start from the furthest point from the master cylinder.
If you are working alone then use a catch bottle with a rubber line attached to the bleeder valve. Add a little fluid to the bottle first so that the line is submerged at all times, thus preventing air from entering the system.
Don’t forget to keep the master cylinder full of brake fluid as you are working. The last thing you need is a dry master cylinder that is allowing air into the entire system.
Well that’s about it in a nut shell. I know that I left a lot out but you have the basics.
If you would like to learn more about ” How to Do It Yourself ” brake jobs then I recommend our latest DVD on Front Disc Brakes. We use a Honda Civic as an example but the info can be used on any front disc vehicle. Just click on the DVD at the top of the page and you’ll be fixing your own brakes like a Pro in no time.
