Rear Brake Issue

I have noticed that only the DR side rear would bite on the brakes (or so it feels and appears that way).

Yesterday finally had a time to inspect both rears.

I do not remember if I replaced the brake hardware the last time I replaced my pads on the rear, however I am missing the anti-squeal shim, springs are there on the Pass side.

I ordered a set and they are made in Japan, soon as in, I will tear it down and see what the problem is. I think I have a seized DR side rear (which has the missing anti-squeal shim). It actually allowed the pads to ride higher so I have the pads sitting outside the rotor.

Whatever it is, I need to debug it, it does not feel safe when you brake hard and your rear tends to sway.

Wow, that would be cause for concern MandyFig. I'm glad that you caught it before it put you in an undesirable situation.

Thanks. The pissy thing about it is that I cannot drive the SC full tilt! Pisses me off.

So took a day off to actually just spend some time checking this out. The hardware kits comes in THU and this weekend I will tear down the brake and bleed them as well.

The hardware kit came in, though advertised as made in Japan, actually showed up made in China. It is labeled AC Delco too.

where did you purchase from?
if Amazon or Rockauto, they will accept and pay return postage due to the false advertising.

Thanks for the advise. For what I paid for it, I will give it a try.

Well sometimes you just want to bang your head. After researching on how to replace the spring kit on the brakes, and not using the information (in several posts here), I lazily installed the kit wrong.

But I have printed the pics and will now have to go back and re-work it.

And this wrong kit installation might have an influence on the rear braking issue I am having. Plus it will give me a chance to bleed my brakes.

Mandyfig, can you point out what is wrong? (Also, please take some after pictures also.)

The way that is shown on the picture is the right way.

The stainless steel shim was incorrectly placed. Mine was not shoved down all the way. The root cause was that the spring was incorrectly installed (upside down) not permitting the shim to slide down in place.

Got both corrected today, replaced with new hardware.

And then bled both rears.

Are our brakes unique enough that if I planned on having someone else replace mine, that I should either go with a dealer or a shop that specializes in Lexus?

I suspect that I'll only need to replace the pads but I'm never sure until I get into something elbow deep and then I'm committed. I'm tempted to take it on if it is only the pads but I also know that the shims and springs need to be handled properly along with using the proper grease to allow the pad and spring to move freely. So that is the basis for my question (also, I don't have much spare time and don't want to get tied up with my car being down for an extended amount of time).

It is a simple job and most probably it will be just the pads that need replacing. You can do it! There is a utub video too. Good luck.

The concern I had was how safe can you raise the car, before you can put in the stand. You will have to raise it high since the wheel will bow low before you can get it off the ground. Just use proper equipment, I have a low profile and long reach lift so it helped and also have a low profile stand.
