00:00 Hi, I'm Christian Hazel with Motor Trend.
00:01 We're going to show you how to replace your brakes at home.
00:03 Good working brakes are essential for your 4x4.
00:13 Not only to deal with steep descents and coming down off obstacles,
00:16 but because larger and heavier tires impart more leverage on your brakes.
00:20 So first, we're going to set the parking brake and take the front tire off.
00:23 Always set your e-brake and support it by the frame
00:29 with good quality jack stands.
00:31 OK, now we're going to take off our caliper and safely hang it aside.
00:33 You don't want to hang it from the brake hose.
00:37 That's that's special.
00:39 Then we can take off the old rotor.
00:44 Throw it away.
00:47 Now we can install our new Duralast rotor.
00:49 So next, we have to depress the caliper pistons back into the bores.
00:58 So if you don't have a dedicated caliper tool, you can get the job done
01:02 using one of the old brake pads and a C-clamp.
01:04 Let it go slowly and gradually.
01:07 The boom or bottom, that's all the way in.
01:09 Now when I install the new pads, they'll fit over the rotor.
01:11 So now we can install our Duralast gold brake pads.
01:14 Then we can reinstall our caliper.
01:18 Give it a good squirt.
01:26 Clean them off.
01:28 Now we can reinstall the wheel and tire, torque the lug nuts,
01:31 and go take it for a test drive.
01:32 You can use an impact wrench to install the lug nuts,
01:35 but don't slot them down too tight.
01:37 Always leave them a bit loose and set your final torque with a torque wrench.
01:40 With this Jeep's half inch lug studs and 32 inch tires,
01:44 we torque the lugs to 105 foot pounds in a crisscross pattern.
01:48 You don't want to over tighten these or the studs can strip.
01:51 And so it'll click when the torque on the fastener gets to 105 pounds.
01:56 Just do a double check.
01:58 We're torqued.
01:59 OK, so we've got the new brakes installed.
02:01 We've got the vehicle turned around.
02:02 Now it's time to take it for a test drive and bed the pads into the rotors.
02:06 So what does it mean to bed the pads into the rotors?
02:14 Well, you're actually transferring some of the brake pad material
02:18 onto the outer surface of the rotor.
02:20 So when the pads clamp down on the rotor, every bit of the pad
02:24 is contacting the rotor face.
02:25 We're going to come up to about 35 miles an hour
02:29 and then do just a gradual stop.
02:31 Do this about three times.
02:33 Now we're going to take it up to about 45 miles an hour
02:35 and repeat the process.
02:37 We'll take the Jeep back, park it, let the brakes completely cool.
02:41 Be good to go.
02:43 So that's an easy at home how to,
02:46 how to upgrade your braking system with some parts from Durlap.
02:49 I'm Christian Hazel.
02:51 Thanks for watching.
