creon Posted March 5, 2019 Report Share Posted March 5, 2019 The rubber on the osf brake Flexi has perished and cracked which means I'd better change it. I've got a flaring kit and it does look as if the metal pipe will fail through disconnecting the Flexi so a couple of questions please. What type of brake connection is it, I know it's M10 but is it male or female. Will it take a bubble flare? The car is an 04 1.0 auc engine. I don't want the metal brake pipe to fail as it will mean a replacement, and the amount of rust on the caliper has me worried concerning the bleed screw. But hey ho!

LR5V Posted March 5, 2019 Report Share Posted March 5, 2019 give the ridged line and bleed nipple a good going over with wire brush -will help you see what is going on better and help tools fit properly. The nut on the ridged line is female the flexi threads into - you hold it in a fixed position with proper brake spanner (if the nut is already rounded use grips) and then you turn the flexi - unless your ridged line is completely corroded it should survive. Same deal for installing the new hose. For the bleed nipple if its still looks dodgy after the wire brush - invest in a blow torch and heat the caliper body around the nipple to expand the metal, look for plusgas or supercrack penetration fluid - dont even suggest wd40 here. Spend a bit of time, cycling between heat, your are not looking for red hot here and then spray the penetration fluid while it is hot - do this a few times before trying the nipple. Worst case if you snap the nipple off you can bleed from the flexi hose Quote Link to comment Share on other sites More sharing options...
