Yamaha Aerox pad retainer stuck!!

[Aeroxdude]

Hi BCF

I have a problem with my yamaha Aerox 50cc, my front brake pads need to be changed, but my problem is, that the pad retainer is stuck, see pictures.

It's almost like the bolt is too big in the end, so therefore it can't be pushed out, I don't know if they have heated the caliber a little bit, before inserting the bolt....?

But I really need some good advice how to get the bolt out, so I can get new brake pads in, and on the road again...

Thx in advance

Jeez those pads look gammy. Willing to be the pistons aren't in much better condition. Rather than wrestling with it it may be worth seeing if you can pick a decent second hand caliper up?

There is so much corrosion all around in that image that I expect it's stuck due to corrosion. Assuming your ditching the pads, penetrating oil and leave for a bit and then remove.

As said, would equally consider a new caliper too.

The fake brembo's on my dna were the same.

Grab a Hammer (small) and punch/tent peg - then tap it out.

Not like its going to get "more" stuck

I think the pistons are still good, but I was hoping that I only had to change the pads, because a new caliber is pretty expensive I think... but I will try to tap it out with a hammer first...
But lets say that I get it loose, when I install the new pads, is it a good idea to use cobber grease between the pad and piston, so it won't get stuck right away...?

[b422063]

It's good practice to use copper grease, if not just to stop the squealing. I'd strongly recommend cleaning the caliper and piston up whilst the pads are out.

[Aeroxdude]

Ok i will do that, and when I get some spare time, i will try to tap out the bolt, and we see how it goes, i keep you updated...

[Aeroxdude]

Update: I got the bolt out, and cleaned it all and mounted the new pads, but when i cleaned it, i pushed the brakehandle, to get the pistons in the caliber a bit out, so i could clean it better, with that result, that the piston got all the way out of the caliber (bad luck ), and a bit of brake fluid got out, i put the piston back in as fast as i could, but i think the seals (i think that's the name for it) may have been damaged in the process, because when i push the brakehandle now, after assembly of the front brake, i have no pressure, i have also tried bleeding it, but no results, so now i have bought new pistons and seals for the caliber, and i cross my fingers, i will update when i've tried that

pop the pistons out again an post a picture up on here

you may be able to get away reusing your current pistons, but its probably worth getting new seals

people swear by using red rubber grease when refitting the new seals, but i struggled an ended up just using shit loads of brake fluid to coat everything in

oh buy some coppaslip too
