Hi guys -
I've been hanging around here for quite a while just reading all the great informative posts.

I just purchased a 2008 LS460L in the last 2 months thanks to all the wonderful things you guys have been saying about them. Couldn't help myself... I had to go and get one!!!

Every car I've had I always did my own brakes disc or drum.

This car has discs all the way around and I heard there's difficulties in changing these brake pads/rotors.

I been browsing all sorts of forums and there seems to be not many people doing these brakes themselves... Sounds like most of you guys take it to the dealer.

Besides taking it to the stealership or some shop can any you guys give me some tips or gotcha's that you ran into along the way doing this job?

I really appreciate any and all information. (Changing the pads? ..., Bleeding? ..., Computer issues?) Whatever advice you can give.

Thanks!

First welcome and congrats!

There is a FAQ sticky at the top of this forum and under brakes it address your question, here is the links.

Thanks Tee. I'll check out the links.

Thanks for the friendly welcome!

Thanks Jlawr.

I'm feeling pretty dumb for not seeing these links.

I appreciate the help and the patience.

Jlawr, is there a PDF of the bleeding procedure?

Since I am removing the rotors and installing new ones with new pads, I'll require me to compress the pistons completely.

So,
I imagine that I will need to open the reservoir to really push the pistons back and that will require me to bleed the brakes right?

Bleeding the 460 brakes has to be done at the dealer, it's PITA process my tech hates doing himself.

There is no need to bleed. But you have to push the pistons back due to thickness of the new pads.

I do my own brakes on ALL my vehicles. I did them on my LS as well. These were by FAR the easiest I've ever done. Why would you need to bleed the brakes??!! Nothing to do with pad or rotor replacement. If you change the CALIPERS, then yeah.

tyrenfroe

Not to be a pest, but aren't you supposed to replace the caliper piston seals (O-rings) when you change brake pads? Doesn't that necessitate pulling out the caliper piston which then allow air into the brake lines? Thus the need for a bleed.

dzone2k

I'm not planning on changing out any pistons or calipers. I always bled my brakes on all other cars I've had in the past because I pushed the pistons flat to the calipers. Have I been wrong all these years? Pushing them flat does introduce air into the lines doesn't it?

dzone2k

I did see that in both front and rear pdf instructions. I don't think thats a regular thing. Just assumed it was a reccomended Lexus process. I'm sure all car companies are reccomending this arent they?

How were you able to do this without damaging the reservoir or overflowing it atleast?

roadfrog

Use a turkey baster (new obviously), and remove a small amount. Be careful, as brake fluid is corrosive to paint!

Thanks guys for all the information!!!
