IS250 caliper replacement

[Lexi-PLURAL]

Hi all

I have seized rear calipers, apparently both (Lexus Sidcup mentioned this a week ago after doing the fuel line recall. However, not a sniff of it on the last MOT done in February this year). 

I've bought replacements along with Eibach discs and brembo pads and a small tub of brake fluid to bleed the lines. Is it as easy as conventional calipers...remove bolts, remove brake line, remove caliper > reverse to bolt new one in.

Or is there ABS wizadry on the rears that I need to think about?

Thanks!

I had the same, 1 caliper seized, but still passed the MOT.  I think it is because so little braking force is generated that it is hard to tell.  Luckily for me, my warranty covered the replacement.

Anyway, yep, it is as easy as any normal caliper.  In fact, the manual guide is pretty straightforward:

Awesome, thanks for that. When it says cylinder, it just means caliper I assume! I've done this a million times on my motorcycles but feel a bit wary on this car for some weird reason. Just need to get my axle stands and jack from the brother in laws and I'll give it a go. What's the worst that could happen?! :D

Yeah, it seems to mean the carrier that the piston sits in.

I think you will be fine   I removed both my fronts to replace discs and pads and it was straightforward.

Just don't forget to use silicon grease on the slide pins (called cylinder support pins in the above guide), and copper grease the back of the pads.

I took my car in to Lexus Bristol last year for recall work to be done, whilst there they always check it over ( for possible extra work ) they told me I had a rear caliper seized, they replaced it FOC.

The only reason I could see they did this was the vehicle had only done 18k although it's a 2008

Technically, it is the Lexus Techdoc, which is available on this site for a subscription fee:

Normally, as long as there are no financial gain, there are equally no damage for the copyright holder, hence it is not possible to enforce copyright. However, I agree with part being "careful", which I think it is the case with above post.

Well, if it becomes an issue then I will stop posting them, but for now, I would rather try and help out fellow forum members.

Thanks for the info and link ; I do not think there is an issue in this case as the material is not being sold ; but care is always needed on the forum
