Trying to trace down noise on the Lexus. Find that the rear brakes may be really messed up. A modern AWD car, with one rear wheel on the ground, should at least try to move. Well I noticed the traction control wasn't even trying. Then I thought about the winter. I knew the tires aren't great, but in snow it had no brakes. The VSC was terrible. Maybe Toyota ABS? I mean, the parking brake helped stop it sometimes.
Maybe the rear brakes just weren't working and pushing the car forward, fighting the ABS?

But I put two and two together. The rear brakes are gone.
Ok, so I take off the top caliper pin, not the easiest but it comes off.

caliper is supposed to flip down..afterall, it has to slide back, no?

First I push with my hand
Then a screwdriver
then a long prybar
then a longer prybar
then a 3lb sledge
ok, you get the idea.

A huge sledge...ok it moved so I can remove the pads. I noticed the pin is unscrewing a bit in the bracket allowing it to rotate back. Needed sledge to get it back.

I think it is new caliper time. Not worth messing with this and tracking down all the little parts. Some of the clips are bad too, that was making the noise.

..I've never seen it this bad. I read they recalled some years of that design.

Now, a visual brake inspection is very misleading. Why? Because the pads look brand new! I know there are at least 20K miles on them.
Unless you really mash the brakes, they don't apply much.

On a modern car, with 4x4,tc,ABS,VSC, etc, this can be quite dangerous!

Sounds a lot more like a case of neglected maintenance than design !

My Lexus was terrible for brakes in our North East Winters. Waaaaay toooo much salt, not neglect. My rotors would seize to the hubs regardless how much grease I'd put on the hubs. I'd have to sledge hammer them off every time I changed rotors. I was forever replacing my sliders also as part of the maintenance.

The Altima in my signature is having trouble with the rear brakes(AGAIN). They're almost frozen. It's a 2015 and I'm on my 2nd replacement set of rears(3 inclduing OE). ATMOF, I'm replacing everything F & R today & tomorrow. Replaced the Front last spring 2019 and the pads are still good but, I'm changing everything anyway.

Need Salt?

I guess its a good idea to tear down calipers then, because the pads and rotors look fine.

Honestly I should have checked them after stopping in the snow.

My rear discs on my Taurus wagon are notorious for seizing up by the end of winter. Lots of snow, melting water and salt. They are candidates for spring “ brake service”.


If you want the job done right......do it yourself.

I don't see any new calipers for that car other than OE, stay away from remans, many are junk right out of the box and those that do work many times fail after a short time.
This is one of the parts that going new OE is definitely worth it if you intend to keep it.

Check Ebay or online junkyards. Maybe even call local junkyards. I just got 2 for my Montero also not easy to find calipers. $65 for 2 front calipers delivered. Advance Auto, Autozone, NAPA all wanted $65 each but needed a week to ship them to me. Ebay ones from Alabama were here in 2 days. They cleaned them up and painted them. Not perfect but very good as mine rusted though on the passenger side twin pistons. Drivers side was fine but I replaced both just to be sure. Now they are working great as I put it all back together today.

I agree, lifetime warranty means you will be changing them for life.

Those are what my continental has. There are two bolts if I recall correctly.

I believe new ones from a Discount Lexus Dealer are $100. I have to call to check if they aren't remaned. Retail is $149.
Good used ones on ebay are 70 or so.
Reman Junk is 50ish.

With shipping cores or buying locally at overpriced autozone that isn't bad.

That sounds like the problem (at least one of them ) right there. If the pins don't come out easy, then the caliper probably isn't floating and your outboard pad might be rubbing against the rotor. What was the relative thickness of the inboard vs outboard pads?

As for rebuilt calipers ... I've used NAPA remans for years now ... maybe on 7-8 different cars ... never an issue. I also like it that they come painted black ... helps to reduce rusting, as I live in the salt belt as well. As for the original post here .... I've found that here in the NE ...even if pads aren't worn, it's almost necessary annual preventative maintenance to pull the pads & clips ... clean the clips up, clean the pins up, reapply lube, and put back together. If you don't, you end up with what the thread starter described.

For some crazy reason they are both equal. Almost look new!

This is the issue with the brakes, they recalled it for some years. Seems they forgot to grease at the factory. Same caliper as mine.

If not done every 2 years it comes back. Many have complaints. Some say Lexus replaced their calipers free. I see why the calipers are cheap.

They are Reman by A1-Cardone. NAPA told me.

I am a big fan of busting apart the brakes every spring, and it's not a bad idea in the fall either and applying grease to the sliding surfaces. Honda M77 (as recommended by The_Critic) is what I use, and it makes about a year on my daily drivers.
