Brake bleeding Q

[Alex321]

Good advice, though a question, if replacing pads and rotors would a bleed be necessary?

Not normally. I haven't actually replaced rotors, but have replaced pads multiple times, and have only ever bled my brakes once.

Replacing the rotors makes less difference, as they are not part of the mechanism operated by the hydraulics.

Just finished a 2nd bleed on the frond and the wheel is new free rolling and the pads are not pushing the rotor to one side as previously so seems to have got me back to where I was at the start

Good.

Generally, I try to never mess with anything that is working correctly, in case I stop it working

As Ming says above, you generally only need to bleed the brakes if they feel spongy (which means there will be air bubbles - doesn't often happen with the mineral oil ones).

Its often not necessary to do a full bleed; fit a bleed cup in place with some brake fluid in it and flicking the brake lever tapping the brake line wll remove any air.

Checked them out, they have only basically copied and pasted shimano’s manual.

But it's very easy to follow. and on two sides of A4.
