Qashqai - Caliper guide pin stuck

[mattemulsion]

I've seen this come up as an issue quite a bit but I'm struggling to find a solution here...
Midway through changing out discs and pads and the lower guide pin on the FR caliper was almost completely seized up. The old pad has worn unevenly.

There's movement in it, I can rotate the pin completely almost by hand but there's next to no movement in or out. It feels almost like there's some kind of vacuum effect keeping it in.

Tried hammering it out and levering it out but I'm getting nowhere. The rest of the caliper is in ok condition and replacing it isn't really an option anyway.

Getting desperate here, any suggestions would be appreciated

Never mind

Walk away and then come back to it.

Oh.

What did you do?

I did that first! ??

Adjustable wrench at the base of the pin, claw of a hammer against the head of the pin. A second adjustable wrench once it started coming loose. Lots of levering. Some tears an swear words. Popped out eventually.

That pic was after I cleaned it up though it was a mess (got another cleaning after that pic, spotless now), the rubber gasket was properly gunked up so it was a vacuum that was holding it in. Sanded cleaned an greased up, went back in like a charm.

Years ago brakes would be stripped and cleaned every 6 months - if you did that it'd be fine. A couple of family members are having recurring problems with rear pads sticking on Honda Jazz's. Maybe it's a 'Japanese' thing.

Roll pin punch and heavy hammer is good to use on these, or a centre punch in a bind if not got a roll pin punch

How are you going to use them in a blind hole?

Didn't realise they were blind on this car, I retract my statement

I'd like to say I'd make this a habit but for the age of the car now it feels like more effort than its worth.

just having the same problem and on investigation it seems I have for years used the incorrect grease on the pins, I tried the local motor factors for the correct grease and drew a blank. Looked on line for pin grease and found a three pack of different greases for brakes and in the only other place i could find the correct grease is Latvia.

Silicone grease is what is required for slide pins, think you could use red rubber grease at a push but don't think it lasts too long.

You can buy little tubs, squeeze tubes etc on eBay for not alot of money. I have some of the Carlube brand

Another vote for silicon grease for the pins
Add in some ceratec for the pad to pad frame contact areas

Yep ceratec is another great one. That little yellow tube seems to last forever too!
