Issue changing rear brake pads
Discussion
Changed brake pads a few times over e years (not this car though, 07 Lexus GS300) but i can't see how to extend out the calliper. Managed to compress in the piston OK but could not retract the calliper so effectively could only put new pad on one side of disc, the pther side I could inly put in the worn pad, too small a gap to put in new pad. Handbrake off, undid bleed nipple, top off fluid reservoir but could not retract back calliper.
Any ideas? For. Kw I have put old pads all back on to tackle another day (or pay someone
)

There are two pins that hold the pads in. They came out OK once the retaining springs removed.
the top bolt (top right of your pic) undos, but the bottom one (top left of your pic) was stiff (but cannot unbolt it as it's just a hinge) and cannot "slide it" it in/out.
the rear callipers were mew from Lexus about 3 years (27k miles) ago. Would they sieze in that tiime?

Sorry to say this, but I think you need to take it somewhere to have them done, I REALLY wouldn't want someone changing brake pads etc on a car who doesn't know what they are doing.
The only other way is to buy a manual & read up on the job before starting to see if you are happy to try it, then look at the job on the car to see if you have the right tools and are still happy to try it. Then & only then should you attempt it but be ready to drop it again if things aren't as planned.
We cannot see/feel what you are coming across & with the best will in the world may give completely incorrect/unsafe advice because of this.

E-bmw - i have done this task (on previous cars) many times without issue, however none of them had siezed pins so I posted this thread in case there was a peculiarity that I wasn't aware of or something that I missed.
I also checked some youtube vids and I did all the steps correctly but it's now clear what tye issue is.
As stated this was an issue with thr floating caliper and not the piston which retracted no problem.

A simple seized pin is an obvious issue that anyone with a reasonable amount of mechanical experience/knowledge would not need to go to the interwebz to find a solution to, I am sorry but I stand my original statement.
If you are going to do work on your brakes on your over 1 tonne of metal capable of approaching 150mph, and wiping out a bus queue of 20 people when your brakes fail, you REALLY need to take it to somewhere that knows what they are doing.
