Raptor 700 Read Brake Pedal Goes Down
The single nearly important safety feature in your Ford Raptor is a adept set of brakes. If your restriction pedal is going to the floor, information technology indicates that there is a serious problem in the braking system.
When the pedal goes to the floor, it'southward normally caused by a bad main cylinder, leaking brakes, bad brake shoes (if equipped with rear drums), and a few other reasons. Nosotros'll go farther into depth on each beneath.
The brakes are a hydraulic system that takes the energy that you lot exert on your Raptor'south restriction pedal, multiplies information technology via the restriction booster, and uses it to stop the vehicle. If any part of this system goes bad, the restriction pedal tin can get to the floor.
We don't recommend driving anywhere with a brake system that is compromised. If the vehicle still can cease, it's not guaranteed that the problem won't get worse.
Symptoms
- Increased Stopping Distance
- Brake Light On
- Restriction Fluid Nether Vehicle
Raptor Brake Pedal Goes to Floor: Causes + Diagnosis
Below nosotros have listed 5 mutual reasons why your Ford Raptor's restriction pedal may be hitting the floor.
Items 1 and two are what you lot want to look at if there is a brake leak. Items 3, four, and 5 are reasons why the pedal could sink to the floor with no leak at all.
i. Fluid Leak
A brake fluid leak is 1 of the well-nigh common reasons that the brake pedal would go to the floor. It also happens to be the easiest to check. All you have to practise is take the lid off of the main cylinder reservoir and check the fluid level.
If the brake fluid is depression, filling it support is not going to fix the problem. The system needs bled. This is due to the fluid in the lines beingness replaced by air whenever information technology leaks out. Information technology's highly likely there is a leak, which you'll need to find.
If y'all've recently had brake piece of work washed, and the pedal is going further to the floor than it used to, you lot may need to bring it back to the store and have the brake system bled.
Diagnosis
- Fill the brake reservoir dorsum upwardly with the appropriate brake fluid for your vehicle.
- Pump the brakes for a few minutes with the Raptor'due south engine running (check the fluid level from fourth dimension to fourth dimension, e'er put the lid on the master cylinder, you don't want more than air entering the system).
- Await behind all four wheels. You should see fluid on the basis by i of them. It'due south highly unlikely that a brake line itself is bad. It'due south much more likely that the trouble is with a caliper or wheel cylinder.
- Jack upwardly the vehicle and remove the cycle in question. E'er utilize a jack stand for condom reasons.
- If information technology's a disc brake in question, inspect the caliper. It's likely to have a leak at the caliper seals at the piston(s). If it is a pulsate brake look at the bike cylinder. This is a very mutual point of brake failure.
- Supplant every bit needed.
- Drain the Brake System.
ii. Bad Master Cylinder
The primary cylinder is the office of the braking system that presses the fluid into the caliper or restriction shoes. When it goes bad, information technology loses pressure causing the restriction pedal to go to the floor. It'south easy to find.
Diagnosis
- Locate the master cylinder. Information technology'due south always on the firewall right about where you would expect it to be in relation to the brake pedal on the other side.
- Inspect the master cylinder to see if in that location is fluid leaking from it. If there is, that'due south proof positive that it needs replaced.
- Replace the chief cylinder if needed.
- Bleed the Brake Organisation.
Keep in listen that if the principal cylinder is low on fluid, that fluid has to be going somewhere. Don't surrender until you find information technology.
iii. Bad Brake Fluid
Brake fluid can go bad just like whatsoever other fluid. When this happens it gets darker in colour.
Diagnosis
Good = Clear to Lite Gold Color
Bad = Chestnut through Blackness Color
The all-time way to check this is to pull a little out with a medicine dropper. Compare it to some new fluid that Ford recommends for your Raptor. If the color is way off, that indicates that it should be changed.
Brake fluid tin can go bad for a number of reasons. It can go likewise hot. Information technology can get moisture in it. When this happens you lot'll get a soft pedal that can go toward the floor. If you lot hit the brakes a few times and the pedal hardens up, that indicates some air is trapped in the lines or that the fluid is bad.
4. Bad Shoes (Drum Brakes Only)
Brake shoes are only found on drum brake equipped vehicles. There will never exist a drum brake on forepart of a modern vehicle. A shoe that is worn down as well far will cause the pedal to sink closer to the flooring than information technology usually would. This would be something to look at if there was no fluid leak detected.
Diagnosis
- Jack up the Raptor. Use a jack stand up for safety.
- Pull the wheel.
- Pull the drum off. This is piece of cake to do. It should pull right off.
- Inspect the shoes. If they wait similar they are nearly worn out supervene upon them.
Tip: If you lot practise replace the shoes, jack upwards the vehicle and pull both drums off. You tin can use the other bicycle as a reference for jump placement. If you don't take ii jack stands, make certain to take a few good pictures of how everything looked before disassembly. A good pair of needle nose pliers can aid when doing this job.
5. Bike Begetting (Disc Brakes)
This is not as likely every bit the items listed above, but a bad cycle begetting can cause the brake pedal to get to the floor as the rotor has different geometry in relation to the caliper. This increment in air gap can cause the pedal to sink to the floor.
If there is a fluid leak this would not exist the problem. You lot should hear and feel a wheel bearing that is this bad, just keep that in mind. Here's more on diagnosing a bad wheel bearing.
Bleeding Brakes
If information technology concluded upwards being a brake leak that caused the problem, and you've replaced the part in question, yous'll need to bleed the brake system. There are 2 means to do this. Yous tin can get a one man bleeding tool, or yous tin use a friend to pump the brakes while y'all do each wheel. Here's more on that.
Conclusion: Ford Raptor Brake Pedal Hits Flooring
There are a lot of reasons why your Raptor's restriction pedal may go to the floor. With enough time and patience, you tin find the crusade yourself. If y'all don't experience comfortable doing that, have a professional look at it right abroad. A weak brake pedal is not something you want to trust with your life.
