5th Gen Calipers
- Thread starter 084RUNNAH
- Start date
i had napa pads laying there. they were 2005 4th gen pads I had purchased a month ago thinking I would need to do brake job since I was getting vibration while braking. When i found stuck caliper, i used them on the 5th gen calipers. They fit perfectly.

Well, I just discovered my front calipers are done. 3 out of 8 pistons are seized, which I discovered during my front brake job today. I did the rears last year, and discovered the seized rotor issues that plague these trucks, so I should've seen this coming.
I used NAPA Eclipse calipers, Centric rotors, and Hawk LTS pads when I redid the rear. Today I had new Centric rotors and LTS pads ready to go on the front when I found the caliper problem.
While shopping for calipers online, I noticed that NAPA doesn't seem to have a matching set of Eclipse calipers for the front in the "13WH" casting (larger brakes, SE) so I started looking for other options and stumbled across this thread!!
The crappy thing is that I have to return my 4th gen rotors to Amazon if I do this. I'll be able to use the pads since they seem to be the same between 4th/5th gen from what I'm reading, but I don't think it's a good idea to use the 4th gen rotors...
Why didn't I see this thread 3 weeks ago before I ordered my parts?! :redbrick:

This morning I found the NAPA Eclipse 13WH calipers (4th gen) on their site. They weren't showing up in the search results on my phone.
Decisions, decisions!!
If I could get NAPA Eclipse versions of the 5th gen calipers, I would just go that route so I could pick them up and exchange the cores locally. It doesn't seem like NAPA has any calipers for 5th gen, probably because there hasn't been a need. I guess that's a good thing!
I see that Rock Auto is a $75.00 core charge for these 5th gen calipers. How much did you all pay for shipping to send back your cores? I've never done core charge parts exchange through the mail, and I'm trying to get a rough idea how much it's actually going to cost me in the end.

$14.00 was taken off of my 150 return for shiping, from NY to AZ

I am very curious if 5th gen owners will start having caliper issues as well. If they don't then that will make me go even more crazy. I just can't figure out why the 4th Gen is the only other Toyota/Lexus model that have these caliper issues. Why why why....
Someone that orders these calipers needs to take them apart along with the original caliper and see if there's any differences.

I'm really interested in this as well. Only thing is that I'm running an 08 SR5 with 17" wheels so I'm not sure if I will have to upgrade rotors in addition to cutting the dust shield or not.
Either way, I can feel my rear caliper sticking so I think its time for a replacement. May as well try it out and see how it goes.

From all the information I've seen, the SR5 rotors are smaller, even if you have the 17" wheels. So you will need rotors.

Awesome, thanks. The rears are noticeably sticking so I'll go ahead and replace those now with 5th gen calipers and new rotors. The front pads and rotors are new (as of 10k miles ago) and calipers are not sticking yet so I'll replace those when (not IF) they start sticking.
Hearing that 5th gen calipers bolt onto 4th gen has made me feel much better about the only real problem I ever worried about with this vehicle.

Just got my rear caliper cores refunded
4th gen rotors could work however you will be pushing the caliper pistons further out as 4th generation rotors are thinner compared to the 5th gen rotors.
As for the rear, I'm using 4th gen rotors with 5th gen calipers with no issues. There wasn't too much of a difference between 4th and 5th gen rotors. Mine had about a year worth of usage

Thanks for the info. I'm going to play it safe and switch my front rotors to 5th gen. My rears are staying 4th gen for now, since I just redid all of that back in November.
I have to wait for the new calipers to ship anyway, so I'll have my new rotors ready to go before they arrive (Centric rotors via Amazon Prime).
I can't wait to get this taken care of so I can get back to my suspension and OBA project! [emoji3]
I replaced my front rotors and pads last weekend. this is the third time for the pads and 2nd time for the front rotors. previously when I replaced the pads, I had to replace the caliper too due to frozen piston.
during the time that I was fixing it last weekend, I noticed that the inside bottom piston is so rusty, I thought it seized. I also noticed that the inner brake pads are seized to the caliper, not moving at all. I believe the reason why those calipers seize are because of the accumulated dirt that goes in caliper where brake pads meet. when it seizes during braking and doesn't come back, it causes the pads to overheat and thus transferring the heat to the piston and thus causing the piston to seize.
To avoid a seized caliper, you'll need a periodic maintenance of the mating surfaces of the caliper and pads and use a caliper grease to grease those areas for smooth sliding of the pads. regular cleaning, like every 2 years when you bleed the fluid would be good enough for proper movement.
please feel free to comment. thank you.

The inner pistons on my driver's side front caliper have seized up and required replacement each year for the past three years. I would say they need to be cleaned and greased every six months based on my experience.
