My backing plates are rusting out badly in the rear. If I'm replacing these, what else may I well replace if I have a few thousand dollars to burn?

06' Sport v8

Wheel bearings? The rotors are new but the calipers i have on the rear's look like they're ready to die as well and it scares me to hear about you guys saying they seize up on the highway. My family and I do a lot of driving across the country.

I would go ahead and replace the bearings and the spindle seals since you have to remove them anyway to replace the shields. Get the bearings here:

Thanks, I sent that gentleman a message. Beside wheel bearings would it make sense to replace the calipers? I hear the OEM will just seize again so what's the general trusted replacement?

Check your Brake lines. My hard lines were crusty AF going to the flex lines and even broke when I was cleaning rust in an adjacent area. I recently replaced the brake hard lines from mid frame to the rear, flex lines to the axle, and hard lines along the axle

I just snipped them to make removal easier. Then put an impact with 6 point socket on the nut to get it out without rounding


Didn't get a lot of pics of removal or install because I was pressed for time, but heres one of final install

The calipers are up to you. It’s hit or miss whether they’ll seize. Since, according to your profile, you live in Queens, I’d at least inspect them to make sure they still move freely. The part that seizes are the pistons, and will be apparent when trying to compress them if they’re frozen/stuck.

I’ve not had to replace mine so don’t know what people are using. I know I’ve read quite a few posts of people buying Napa lifetime warranty calipers so you don’t have to pay again in the future when they fail again. Don’t know the longevity of those though.

I wholeheartedly agree with that. I recently bought a 2007 V8 4WD Sport Edition, and was checking the brake pads and saw my rear brake lines; they look a lot like your old pictures. I am going to procure all those parts you mentioned and replace them.

Any difficulties with the install? Anything to be aware of?

In addition to those parts, I used the extended flex lines from Apache offroad.

As far as difficulty, definitely easier with two people. The ones that run along the tank and over the frame are a bit tricky. Dropping the tank about 1" with the strap bolts gave some extra room. I believe we fed the lines from the rear over the tank towards the front. Another thing to keep in mind is pinching the lines between the tank and the frame rail, and that's where having a buddy guide while another pushes really helps

Yup, mine look similar. Was wondering about that. Thanks a million!

I may keep the calipers then, mine really don't look so bad and apparently the sport version is better.

What about the bearings? That should be replaced if replacing the backing plate since they have to be removed anyway ya?

Rear wheel bearings look like a major pain in the butt from what I've seen, so I'd leave it if they're fine

Those clips show they're not for my model on Toyota's site. I can't seem to find the 06' v8 equivalent.

They're a pretty generic part. They're a little arched clip that holds the brake lines into the brackets. I just went to toyota parts, entered my vin, and ordered everything from those mid frame hard lines to calipers.

Holy crap, I totally missed that the stuff you’re working on is the rears. Those bearings I recommended are for the front. My bad lol

If you replacing rear backing plates, order everything for a full replacement. Bearings, seals, parking brake pads, ect. Your going to regret not doing so.
I did a regear and put axles back in, 3 months later had leaks. You dont want to have to pull all that apart 2 times, let alone having to deal with the parking brake assembly.

can't speak to the lines, but i just replaced the rear brakes on my '07 v6. had an indie shop do the labor. replaced the calipers, pads and rotors with toyota products (calipers were remans). a lesson learned was when buying calipers from toyota, parts that come packaged with aftermarket are sold separately with toyota. it took several appointments to get it right, because the slide pins were frozen into the brackets (originals with 220k).

long story short, had to additionally buy the rear caliper brackets, bolts and pins, rubber bushings and boots. all told, an additional $210.

went with toyota calipers because i had repeated issues with cardones on the front. warranty replaced the calipers, but not the labor or my time.

Thank you, this is very helpful.
