Renault Repair Questions? Ask a Mechanic for Answers ASAP
Hi..there..Im Rob, A fully certified vehicle technician in the UK and will be assisting you with your question today.
Are they getting/noticing air bubbles out of any of bleeders,clear line at all when they try to bleed it?
Are they bleeding using the pedal or pressure bleeding?
I take it they have checked for leaks and overheating at any of the wheels causing brake fade?
What air out of all 4 front and back? or just one side/bleeder or both rear?
Sounds like the right side is your problem then,what condition is the caliper in? has been any signs of overheating on that side...i take they have carefully inspected the flexi line brake line ferrules for excess corrosion..could well be the caliper... if you where getting alot of air out the back then i would put my money on the compensator valve over the rear axle as these are very common for failing,sieze and drag in air... but if you getting out the right front side mostly,alot of air in that line.the lines that feed those comes directly from the abs pump...then it can only be either the caliper, the flex line or the solid line or brake union dragging in air.... so long as they have properly bleed the master and activated the ABS valve block incase any air is trapped in it after the master was done....
