How to remove caliper guide pin's rubber boots
Hey whats going on
I'm trying to remove the caliper guide pin to clean the inside bore and rubber boots. I always thought the rubber boot was just pull and tug but upon further inspection it looks like it is stuck to the inside of the chamber. I tried tugging a little but it didn't want to come out. It feels like if I tug any harder, it will rip. Anybody have any ideas on how to remove that rubber boot?
Thanks.
Also, I got some new slide pins just in case mine were damaged but the indented area where the black cylinder goes on the guide pin didn't come along with it. Any idea on how to remove the old black cylinder from the pin ?

Try a twisting motion to break the bond between the boot and caliper pin bore before attempting to pull ..or you can use the blunt end of a pen to carefully pry the edge of the boot from the caliper pin bore. Did you buy new oem pins or are they aftermarket?

I always leave the rubber boots alone, you can clean inside if you just spray brake cleaner in the hole and spray compressed air in to dry. I have had problems with aftermarket boots not fitting Toyota/Lexus and ending up reusing my old ones.
To remove your plastic from the pin I would try spraying with brake cleaner, then lubricant spray, then maybe a couple of really tiny flat head screwdrivers, or smash it to break it up, then fish it out in pieces. I have had better luck with aftermarket slide/guide pins actually fitting.
Always lube the new pins with Sil-Glyde.

Wait, so is the boot supposed to be plug and pull from the caliper bracket end? I have no problem getting the caliper pin out from the boots, the other side is my issue. It feels like it is build into the bracket. I just need to know if it is build into the bracket or it's just seized from all the corrosion.
The metal bushing may need more persuasion. Here's some tips in post #5 which should apply the same in the 3rd gen. https://www.clublexus.com/forums/rx-...11#post6808026

the long swabs are great for applying the hi-temp brake grease. I use the brass bottle brushes used for gun cleaning to get out the old dirty grease with some brake cleaner. Clamp the handle on a drill and it makes work really quick and easy. They can be found cheap on ebay.

You may need a new caliper bracket. On my HS250h I had a frozen slide pin on the rear driver side caliper because, being a hybrid the brakes last forever and I got lazy about caliper maintenance. The aftermarket rubber boots would not fit the new bracket so I ended up using my old ones after I hammered the stuck slide pin out of the old bracket.
I later found out I should have just bought a used caliper on eBay as they usually include the bracket, just look at the photos. There are many on eBay and the price was half of a new bracket. Then you have a spare caliper too!

My friend that works at lexus parts just confirmed that the rubber boots are not sold separately. It comes as a unit with the bracket, therefore it is probably build in the bore and cannot be removed easily without damaging the boots.

I just finished servicing my brakes. The rubber boots are fairly easy to remove. Just pull gently on the rubber at an angle while pushing the boot sideways. It will pop right out. Lubricate the end of the rubber before installing and it will slip right in - and come out easier the next time.
