I recently got my rear tyre changed, but almost immediately I stated hearing a loud rubbing from the back brake, It goes away momentarily when I lightly press either brake, Ive taken it back to the garage 4 times but he can't find out what the problem is, could he have put it back together wrongly? Any suggestions please .
 
Yes he could.

Did he take the brake pads off for any reason?
Should not have had to but some not familiar with the bike might do that. If so, the pads may have not been installed correctly - there's tabs and notches and a clip that have to be in there just right.

If he did not take the brake pads off then you might have bearings that are going bad, or already bad... sometimes a tire change will expose that more before they're completely gone.

Is the ONLY thing the mechanic did was a tire change?

Hi Mellow
Yes the only thing he did was a tire change, when I took it back each time he took the Pads out and to check wear and put them back in, I wonder if the clip is mis aligned or missing, I had an NC750 x that the clip was a nightmare to seat, I'll check, thanks for the info
 
It's possible.. did he check the wheel bearings? That is a weak spot for the ST1300.

This shows some of the orientation:


Awesome document here:

 
And this is what you need to check for if the damage a clip.

What's often overlooked in discussing the orientation and installation of those clips is the function of those little tabs Larry spotlights in his pictures.

Notice how the springs on the right of the clip with the tabs are narrow and those on the left without clips are wide.

The tabs on the narrow springs are designed to retain the fixed pad in place against the outer part of the caliper opposite the pistons.

The wide springs are designed to maintain tension on the floating pad which is moved by the pistons. It's wide so it can maintain tension on the backing plate of the floating pad as it moves closer to the fixed pad as its friction material wears through the life of the pads. And of course the caliper floats on the caliper pins to keep the whole assembly properly positioned on the brake rotor as they wear.

Once I understood why the clip was designed that way and what it's doing, the proper orientation and assembly requirements are always obvious to me.
 
Is this an ABS Bike, I've had a ABS sensor mis-adjusted by a Tire changer that causes a rythmic scrape.
This was on an ST1100 but just the same check the ABS gap if you have it.

Hi STrider, that is great info, I will investigate, I do hope it is something as dimple as this, thank you very much.

Hi Slydnbye
Yes it is ABS model registered 2015, now im getting worried, I'll have a check tonight, thanks again.
