You'll need:
- Brake pads: HB683Y.651 LTS Brake Pad
- Brake pad wear sensor front: URO Parts SEM500050 Front Brake Pad Sensor
- Fluid withdrawal tool: Car Fluid Withdrawal
- Brake fluid: Motul DOT 5.1 Brake Fluid - 1/2 L. 8070HC / 100951
Now for the procedure:
First of all remember you have to remove your front wheels and suck some of the brake fluid out of the reservoir. So I recommend using this tool: Car Fluid Withdrawal to suck as much of the brake fluid as you can from the reservoir, Then properly set up your car and remove the front wheels. Wearing goggles is not a bad idea since that clip love to jump.
With a hammer and a thin punch start tapping the brake pad pins out. Be careful and make sure you make a clean hit with the pin so you don't cheap that beautiful caliper. In my case the beautiful caliper is hidden in all that dust... and make sure you hold the punch straight not like in the photo, I just did that to take a photo. Repeat for the bottom pin.
As you punch the pin out of place, it'll become loose and you will be able to take it out by hand, or pliers, but put your hand and hold the tension clip so it doesn't jump (wearing goggles is not a bad idea at this time). Then neatly put your parts aside.
With the pins and slip out of the way, you can place a screwdriver between the rotor and the pad and pry to push the pistons back. Make sure that the tip of the screwdriver is pushing against the pad so you don't scratch the rotor and create another problem since we are not changing them. When the pistons are all the way back take out the respective pad.
Now go to your pads, make sure you grease the sides of all four pads with white grease.
Place the new pad in place, and repeat the pushing back of the pistons for the other brake pad. Then take it out and place the new pad in its place.
When both pads are in place, put the pins and the tensoin bracket back in place, use goggles, and tap them with your hammer first like in the photo below, and then with your punch. Make sure the braket is clean and dead in the middle, you can adjust it with the screw driver but always wear goggles in case that sucker jumps.
With all you pieces back in place, is time to go to the other side, assuming you started on the passenger (right) side. If you started on the left side where your sensor is, then you have to remove the sensor (back before your removed the pad) and place the new one back in place. To do that read on.
Remove the brake pad wear sensor, you can just pull it with the pliers. If it comes apart is ok we got a new one :D.
Look at how the old sensor is routed and clipped in place. Look at the pic in case yours wasn't properly routed.
The sensor connects at the following little box. The box opens flapping down.
Notice the white wire on the following pic, that's the routing of the new sensor. Make sure the sensor is connected like the old one was, and is properly routed so it doesn't rub anywhere. Then make sure the tip of the sensor clips cleanly on the pad so you don't get a light. I place the tip by hand into the pad then push it carefully with pliers.
And that's it, after you've done this procedures for both sides (only the left side has a brake pad wear sensor) just make sure you fill your reservoir with new brake fluid and depress the brake pad several times with the car off. The pedal should evenually feel hard. This is to make sure everything is tight. Make sure you use the right pads, any crappy brand will make noise and won't perform like Land Rover brakes do.
