I think this brake ain’t looking right after installed the Arashi foot pegs..

 

[bryannnnn]

I don’t know what it could be wrong

 

[sbk1198]

You didn't notice the extra drag on the wheel when you were riding it??

Yeah that's toasted though. New brake lever put pressure on the master cylinder, applying brake pressure, then overheated while riding causing more friction.

Can't tell exactly wut I'm look'in at; the brake's dragging, wore all the pad material away?

didn’t noticed the dragging but somehow I stopped n looked at it saw smoking...I think I installed right tho

This is the first thing that came to mind

Hindsight is a wonderful thing I know but if your doing that sort of work then do it on a rear stand so you can spin the rear wheel easily and check that all is well before riding away. Noise is more of an indicator and will often will tell you more than a visual inspection.

Did you check the wheel spin while on the rear stand after you installed them? I have seen his recently on an R3. Someone installed a set of Vortex rear sets on the bike and didn't adjust the push rod right and same thing happened. Rear caliper was smoking and brake fluid was boiling. Could barely move the rear wheel at that point.

Wow. That's super trashed. Surely the sound of the metal on metal would be horrendous? The drag must have been significant surely?
You'll want to remove the red height adjuster disk so the brake pedal can come up to a reasonable angle. I think I mentioned that problem on my install post.
Also the brake lever return spring is much better to route through the center of the master cylinder bracket or on the right hand side of the bracket, so its captured.

 

[bryannnnn]

The pads are very closed to the rotor. Don’t know why...

 

[Grantman]

You've got no pads left, just the spectacularly trashed back plate. The brake piston doesn't look good either, nearly popped out. A caliper boot is also torn. From that picture, I'm definitely thinking a complete rebuild.

The brake pedal red height adjuster must be holding pressure on the brake lever. Otherwise it'd return to a resting state and there'd have been no drag.

 

[Grantman]

This is what yours should look like. You've even got the rubberised shifter peg on the wrong (brake) side. *edit, my mistake. I didn't realise the 1.0 Arashi version came with two rubberised pegs.

Plus new rear pads and brake fluid obviously.

*You'll need to check the disk itself isn't warped. If it's still straight, I'd keep it.

 

[sbk1198]

I'd just get another caliper, pads, and rotor. Don't have to be new, but as long as they're in good condition.

Check eBay, I'd bet there are several to be had for cheap $.

Sometimes that just works out better for both the installation and the peace of mind--no worries that you missed something.
