Take off the wheels
In order to change the rear brake calipers on your vehicle, you will need to take off the wheels to have full access.


Don’t forget to put the wheels under the vehicle!

Release the parking brake
It is now necessary to release the parking brake in order to clear the grip of the drum brake shoes on the disc.

Retract the piston
Insert a flathead screwdriver to the outer extremity of the oblong hole located on the front of the brake caliper.

Lift it off using the screwdriver as a lever by pulling it towards you.This will cause the piston to retract slightly, so that the caliper can be removed more easily for the next steps.

Sometimes this is not enough to remove the disc. You will have to remove the shutter cover located on the disc with flathead screwdriver. You can now reach the adjustment mechanism of the brake shoes, and retract the brake shoes until the disc is free.



Loosen the slide pins
With a ratchet and a 14mm socket, unscrew the slide pins.

Get the new assembly and unscrew the slide pins.

You can now remove the caliper.


Take the new caliper mount.

Reassemble the caliper mount by screwing first by hand, then with a 19mm wrench to lock them in place.





Finish tightening using a torque wrench.


Tips before installing the new caliper
Place a container to collect the fluid under the caliper, since the brake fluid may leak out.

Using a ratchet and a 11 mm socket, unscrew the banjo screw connecting the hose to the caliper. It can sometimes be hard to unscrew. It’s also recommended to loosen it before removing the caliper.

Finish unscrewing by hand.

Next, separate the brake hose from the caliper.Remove the copper gasket from the banjo screw.


Here’s a tip! You can limit brake fluid leakage during this operation by plugging both sides of the banjo screw with banjo shutter pliers.

If you’re not replacing the hose, clean the hose and caliper with brake cleaner and paper towel.

Don’t forget to clean the nearby parts with brake cleaner to remove all traces of brake fluid.

Grab the caliper. Place it on the rear control arm.

Remove the old copper gasket from the banjo screw.


Get the new copper gaskets.

Put a seal on the banjo screw and install the assembly on the hose.



Then put the second seal on the banjo screw.The hose has a locating piece that holds it in place in the caliper once tightened.

Screw the banjo screw, that connects the brake hose to the caliper, back in.


Using brake cleaner and paper towels, clean the contact surface between the brake caliper and the brake hose.


Place the new brake pads
Grab the new pads, and lightly coat the ends with copper grease to help them slide more easily.


Insert the new pads into the caliper mount by sliding them in.


Put the brake caliper back
Lubricate the slide pins with silicone grease to facilitate sliding. Put the brake caliper back in place and screw in the slide pins, by hand at first.





Screw them in using a socket wrench and a 13mm socket.

Bleed the brake fluid system
When replacing a brake caliper, you need to bleed the brake fluid system to remove air from the system. To do this, we suggest watching our video “How to bleed the brake fluid system Nissan Altima”.

After bleeding, remember to clean the caliper-disc assembly with brake cleaner.




Put the vehicle back on the ground
Then, you will be able to put the wheels back on your vehicle.

Put the car back on the ground and block the wheels properly.


Don’t forget to screw the brake fluid cap back on before starting the car.

Pump the brake pedal
Attention! Before using your vehicle again, start your car, and pump the brake pedal a few times to push the brake pads together again.


Safety tips
Try to drive smoothly and avoid sudden braking for the first 30 miles or so, to avoid glazing the new pads.
