Rear Brake Job w/new rotors

I decided to take a few pics of my brake job and turn them into a DIY. I know there are a couple threads out there, but IIRC, they don't do a step by step with pics. Here goes.

First, break the lug nuts loose. Lift and support the axle with jack stands. I leave the jack in place as an extra measure.
Remove the wheels and attach a bleed container to the bleeder fitting. The container should have a few ounces of clean brake fluid in it.



Loosen the bleeder and compress the caliper by wedging a flat blade screwdriver between the brake pad and the rotor, then pry the pad away from the rotor. Do not go between the pad and the caliper piston as you can tear the dust boot or damage the caliper piston.


Remove the caliper from the caliper bracket and lay it on top of the axle. Do not let it hang by the brake hose.



Remove the brake pads from the caliper bracket.


Remove the caliper bracket.



Clean or replace the brake hardware that the brake pads fit into.



Remove the disc brake rotor. If it is seized to the hub, use the threaded holes provided by threading a bolt through the hole to press the rotor from the hub.




With the rotor removed, inspect the parking brake shoes and clean or replace if necessary.


Compare the new rotor to the old one to be sure they match. It's not uncommon to find brake rotors that are misboxed from the manufacturer. You will also need to transfer the rubber inspecion hole plug from your old rotor to the new one. If you have your old rotors turned/machined, remove it before doing so.


Clean the new rotor with brake cleaner and dry it with a paper towel. Don't use a shop rag. The fibers melt to the pads and rotor, not to mention the detergent they are washed in. Paper towels or compressed air is best.



Clean the hub with a wire brush and apply a light coat of anti-seize compound. Don't use too much. If it gets behind the rotor, it can warp it as the lug nuts are torqued.



Install the new (or machined) rotor and run up one lug nut finger tight. This will hold the rotor to the hub while you install the pads and caliper later.


Your new brake pads should be chamfered on the ends to prevent squeaks. If they are not chamfered, it's ok to add the chamfer with a bench grinder or file.



Apply brake caliper lubricant to the back of the brake pad...NOT THE FRICTION SURFACE... to reduce vibration transfer to the caliper. This will reduce squeaks. Also apply lube to the ends of the pad where they slide in the caliper bracket.



Apply caliper lube to the caliper bracket anywhere the brake pad will contact it. Also lube the guide pin holes where the caliper attaches to the bracket.



Reinstall the caliper bracket.


Insert the brake pads into the caliper bracket. Clean the caliper guide pin/bolts and lubricate them. Lubricate the caliper piston and install the caliper.






Top off the master cylinder with DOT 3 brake fluid. Remove the lug nut that was installed to hold the rotor in position, then reinstall the wheel. Repeat for the other side.



Don't forget to pump the brakes to position the pads against the rotors before driving it. There is no reason to bleed the system. Using this method, there is virtually no way to draw air into the brake lines. As you compress the caliper, old fluid is pushed into your bleed container. As the caliper reaches full compression, tighten the bleed screw before removing the hose from the bleeder.

Remember to ALWAYS torque the wheels to specification by hand. These trucks are prone to rotor warpage and overtightening the lug nuts is an easy way to warp them.

I'm going to take a few pics of the bleed container I made out of the brake fluid bottle and explain why it's worth using one.
I also want to add that you need to pump the brake pedal to seat the pads against the rotor before driving the truck. Don't use full strokes to do this. Use slow short strokes. This way, you avoid pushing the master cylinder plunger into unused territory. It can ruin the master cylinder on older cars with corrosion in the bore. Better safe than sorry.

I've used tons of different brand of brake parts over the years and, for the price, Centric is the best I have found. I use PosiQuiet pads, but not the extended wear version. The "extended wear" pads are more dense and, therefore, squeak prone. The Centric pads don't require burnishing and are the most squeak free ceramic brake pads I have ever used. I have also never had to warranty a Centric rotor...even with their cheap line.


I also wouldn't recommend using a vacuum bleeder on these trucks. I don't use vacuum bleeders at all anymore. A pressure bleeder on the master cylinder has far better results. I've seen cars have no pedal whatsoever after conventional bleed procedures. German cars and GM trucks are notorious for it. A pressure bleeder works every time and will correct the "no pedal" problem created by conventional bleeding. Many systems also require a scantool to actuate the ABS bleed procedure. Using my method, you remove the old fluid from the caliper without requiring a bleed afterward. I would not attempt a full bleed or fluid exchange at home without having a pressure bleeder and scantool with ABS capability handy.

Here's some info on the bleed container I used. It's just a brake fluid bottle. I drilled 2 holes in the lid. One hole is just a vent to prevent pressure buildup in the bottle. The other hole is for the clear plastic flexible line. I drilled the hole so the line fits snugly and had to be forced into the hole. That way you can suspend the bottle if you need to and it helps keep it more stable to work with. The flexible clear line is simply aquarium air line from WalMart. It's cheap. Cut a length of line long enough to keep the bottle out of your workspace and below the caliper or wheel cylinder you are working on. It should reach the bottom of the container when the lid is installed on the bottle. The container should have a few ounces of clean brake fluid in it. This will ensure that no air can be sucked back into the brake system. Once you attach the line to the bleeder, open the bleeder about a quarter tuen and begin compressing the caliper. Do not stop until there is no air remaining in the plastic line. You now have an air free passage to reserve brake fluid. In the case that someone were to mistakenly pump the brake pedal or open another bleed fitting with one bleeder still open, the brake system will pull brake fluid from the bottle, not air. Here are a few pics of the bleed container.

Nice write-up, thanks for sharing. I had to run out to my truck and check the brake fluid type. It is DOT 3. My past few german vehicles have all been DOT 4, so I was suprised to see DOT 3 was still being used.

I'm not sure I'd use that much anti-chatter grease on the pads though. It's going to ooze once it gets hot.

Yup, most American and Asian cars use DOT3, while most European cars use DOT4. I keep both on hand since we also have a BMW.

The Permatex synthetic lube is a high temp grease. Your rotors will probably glow in the dark before this stuff gets runny. I've used it for many years without an issue of oozing.

Thanks guys. I have all the stuff for my front brake job. Things have been hectic around here, but I hope to have time to do them in the next couple days. I'll do the same write up and add it to this thread and ask a mod to change the title to front and rear brake job. Stay tuned.

I wanted to add a couple PDF files to this thread complements of Mendonsy...

Dealer recommended my front brakes changed when I hit 36K. They said back was still okay. What mileage did you have when you did the rear SoCal? What is the recommended mileage for changing rear. Also, the rear disc you replace looks like it won't rust. Are they stainless steel or something?

I did the rear at about 65-70K. Mileage depends on how hard you use them and what friction material you have. Toyota uses ceramic friction material from the factory. Adding a trailer will accelerate brake wear, as will racing up to stop lights then slamming on the brakes. Mountain driving will tend to wear brakes faster, too.

These are bonded, so when the friction material reaches 1/16" at the thinnest point, it's time to change them. There is no recommended mileage for brake pad replacement.

No, they will rust.

To add, the dealer replaced my front pads and turned the rotors at about 25K due to vibration and steering wheel oscillation on braking. Fronts are getting new rotors, too.

i would almost swear that was me doing that brake job, except my screwdriver is red lol.

It is really amusing to see an old school guy do brake jobs and skip alot of those steps. you would be really surprised how much that lube and bleeding the calipers in that fashion can improve the pedal feel.

Fantastic write up!

Thanks for the great write up...looking forward to the one for the front brakes.

I have a Motive pressure bleeder which I have used on other vehicles with great success. I haven't flushed the Tundra's brake system yet, but plan to next year as I believe in doing it every three years on a street driven vehicle that is not tracked. You mentioned needing a scan tool to activate the abs pump to do a thorough flush. Is there danger of trapping air in the system if you don't use one?
