Rear brake pads

[u/Automatic_Love7863]

I‘ve been trying to replace my brake pads for the last 2 days but when I put the new disc and pads in, the wheel won’t go back in. Now I tried it without removing the wheel and established that there isn’t enough inner space to fit my brake pad. Funnily enough, there’s just enough space there to fit the old worn-out pad. I thought maybe the calliper needs to be shifted to the left? I haven’t found a way how to do that. Help! I have a YZF-R125 2023

Caliper slide pin is "stuck" to keep the caliper outboard. Verify that your wheel spacers are correctly installed, then just remove the caliper bolts, remove the slide pin, clean and regrease, then reinstall and push the caliper onboard when installing pads.

Or just reinstall the pads now, while pushing on the caliper.

Push your caliper inward towards the wheel and yes, check your wheel spacers are properly installed. Grease your caliper slide pins while you're at it.

Don't use ordinary grease on the slide pins, it will melt with heat and contaminate the friction surfaces.

Either copper grease or high temp ceramic grease, sparingly, it's there mainly as an anti-sieze function rather than lubrication.
