accidentally hit the brake lever when calipers are removed

[potatobroxd]

Yep it happened, i was removing my front wheel when i accidentally hit my head on the brake lever when standin up. Now the brakes wont fit the disc and im not sure what to do next, please send help

If you were close by I'd have lent you my tool for spreading motorcycle caliper pistons, only way would be use a longish spanner between the pads but try not to damage the pad surfaces

Release reservoir cap cover, push pistons back in with g clamp

Make sure you don't pop one out completely

First try pushing the pistons back with your fingers. You need to push both at the same time if you have opposing pistons. If you're lucky, they'll slide right back in. If they're a little stiff and you don't have the correct spreader, a suitably sized piece of wood will help lever them back in without causing any damage.

I'm still a novice with diy maintenance, by the pistons do you guys mean the part i circled with yellow stains on? And i should remove the pads as well i believe?

[Bender]

Yup, remove pads and see if you can move them

[fullscreenaging]

Yes. Remove pads and push pistons back.

Once you’ve put the wheel back on make sure you pump the brake lever to push the pads back onto the disc

The part with the yellow stains ( Rust ) should be gleaming silver before you push it back in . One way to push the pistons back in is to stick the old pads back in and just widen the gap with a tyre lever or a big screwdriver . Dosen't matter if you damage the old ones .

I managed to push back the pistons today but when i put everything back together the front brakes drag? I torqued everthing back together before pressing the brakes, did i do something wrong?

[Mississippi Bullfrog]

It's not unusual for discs to drag slightly when first replaced. So long as the wheel spins under moderate hand pressure it's ok. Obviously if it's really stiff to turn the brakes are binding.

Could be piston sticking too, give it a ride, see if it improves.

Just to say... great forum for advice, etc.
