Hello and thank you for reading this message.

Is there a link please for bleeding the brakes? After fitting new rear tyre then reassembling, back brake still too soft even after filling brake fluid reservoir and pumping back brake handle with caliper fluid nozzle loosened.

Thank you.

Generally to bleed a hydraulic system you fit a flexible tube over the bleed nipple on the caliper and submerge the other end of the tube into a jar with some fluid in covering the end of the tube.
Then with the nipple open squeeze the brake lever slowly and repeatedly until no air bubbles come from the tube in the jar. then with the lever held in close the nipple. Once the nipple is closed the lever can be released and system bleed. Keep the resevoir topped up.
This is the simplest way.
Wondering how removing and refitting the wheel has caused the issue, it shouldn't.

Thank you for your helpful reply!

To refit the wheel, I had to extract the brake fluid to then be able to push the caliper pot back in, so in turn the brake pads would fit over the disc.

Thank you again.

@pdig You should be able to remove the wheel without draining brake fluid.

For future ref' if the pads are stopping the disk entering between them, use a soft tool like a plastic freezer ice scrapper and lever the pads back, all the way if need be. This will push fluid back to the reservoir so don't let it overflow.

Once the wheel is back in, pump the brake lever repeatedly until the pads resume there correct position. Do this before riding the bike.
