Re: Megane II (2005) Front discs & Pads replacement?

By rights you should clamp the flexi hose that goes to the caliper and open the bleed nipple on the caliper so when the piston is pushed back into the caliper the fluid it moves comes out of the nipple and doesn't go backwards through the system!

Most will say it's not necessary and to be honest I've risked not doing it on my own car, but this method should be used as modern brake systems with ABS etc don't like the fluid to go the wrong way through the system.

Also when everything is fitted and you need to pump the brake pedal to seat the pads on the discs or when bleeding the brakes only ever push the pedal as far as it would travel under normal daily use....don't push it right down to the floor where it never normally goes. If you do you run a very big risk of damaging the master cylinder seals as they will be traveling to a part of the master cylinder bore that is never used, this area will more than likely have some corrosion on it and this may damage the seals.

Other than that lot, its a doddle...
