Brake calliper advice

[Gaverick]

Hi guys,

I'm upgrading the callipers in my Fabia vRS. I've changed a calliper before and I'm confident working on cars however I have one uncertainty.

Obviously to change the calliper I need to loosen the brake line and then bleed the new calliper. What I'm not sure about is do I only need to bleed the two callipers ill be changing, or will I have to go round and bleed every calliper when I've only changed the fronts?

Thanks for any advice.

That depends on how well you seal the system when changing the calipers over. There's a good chance that air could make it right back through the system as the brake pipes drain.

Realistically, you should do them all. It always pays to be safe when you're talking about brakes.

unscrew the brake filler cap, put some polythene air tight sheet over it and re seal the cap back down, will create an air tight seal. Then clamp the flexi hose (if there is any) going to your caliper of choice to stop fluid escaping, though obviously after removing the caliper there will be that little bit of air in it, so then feel free to bleed that caliper after removing the polythene.

However, personally I'd bleed all 4 corners, but it depends if it looks like the bleed nipples are going to snap or be easy to take out. Snapped bleed nipples = either new caliper, or if its drums new valves.
