Front Brake Job questions

Regardless of brand and model it is good idea to bleed out instead of pushing the fluid back. Some manufacturers instruct that in shop manuals even. Hose should be clamped but no need to squeeze crazy hard. A tube to bleeder is a must so that you dont squirt the fluid all over the place

i admit i dont use this method each and every time. And shops may be equally lazy. Benefit of the method is that you get ”fresh” fluid to calipers and since you dont pump the fluid back and forth, possible gunk in the system stay wherever its settled.
