Introduction

The calipers on your car are what push the pads in to the rotors when you hit the brakes. Pretty important stuff! They are exposed to substantial heat, brake dust, dirt, water, and in certain climates road salt.

So it's important to check them when you replace your pads and pull them off to clean them, rebuild them, or replace them if needed.

Please note that when working with brake fluid that it is extremely corrosive to paint. If it gets any painted part on your vehicle be sure to rinse it thoroughly.

As you proceed through this guide be sure to collect any fluids in a suitable drip pan and also to dispose of old fluids properly.

You will need to remove your wheels before you start. Before beginning on removal of the calipers you should drain the brake fluid from them.

  • Before beginning on removal of the calipers you should drain the brake fluid from them.

  • This is done through the bleed screw on each caliper.

  • Loosen this and let it drain in to a proper drain pan.

Next you will need to remove the soft rubber brake hoses. You will have to start by disconnecting the rubber hose from the hard line connection up inside the fender well. Then you can loosen it from the caliper and remove the line. This takes a 14mm wrench for the soft hose and an 11 mm wrench for the brake line.

  • Speaking of the rubber hoses, this is a great time to replace them with new parts if they show signs of age since they are already off of the car.

Next use a large ratchet wrench with a 19mm socket to remove the two bolts that hold the caliper to the vehicle.
  • Next use a large ratchet wrench with a 19mm socket to remove the two bolts that hold the caliper to the vehicle.

  • These bolts are in very tight, and had thread locker on them from the factory, so you may need a very long wrench or a breaker bar in order to get enough leverage to remove these two bolts.

  • Hold on to the caliper as you remove the second of the two bolts so it doesn't fall when you remove the bolt.

Deck the Halls
With tools and Fix Kits
After you have completed your work on the caliper, such as removing the old pads, and cleaning them up, they can be re-installed. Or, if you have new calipers, this is the time to install them. Before installing the caliper bolts be sure to apply some thread locker to them. Use the blue thread locker than can be removed with hand tools, not the red thread locker as that needs heat to remove.

  • Hold the caliper up on the rotor and line the holes in the caliper up with the bolt holes in the steering knuckle. Get the first bolt started by hand.

  • Then, start the second bolt by hand as well. Doing so helps ensure they do not become cross-threaded.

Then tighten the bolts down until they seat against the caliper. Do not tighten them all the way down with the normal ratchet wrench.

Switch your 19mm socket to a large 1/2 inch drive torque wrench. Torque both of the caliper bolts down to 115 nm/85 lb-ft.

  • Before you drive the car you must bleed your brakes of air since you opened up the system. Never drive the car without bleeding after you've worked on the lines, or calipers. [无效指南链接]

An important note - if you are removing and replacing the front and rear calipers at the same time be sure to keep the front and rear bolts separate.
  • An important note - if you are removing and replacing the front and rear calipers at the same time be sure to keep the front and rear bolts separate.

  • This is because they are different designs. While you can use the rear bolts on the front calipers, the front bolts will not fit on the rear calipers.

  • Front bolt, with a shoulder

  • Rear bolt, no shoulder, all thread

Conclusion

When finished be sure to take a test drive before going on a long trip.
