Re: Megane III Brakes Problem

When you say the pedal goes down, does it drop under pressure,,try this test,,,get in the car dont start the engine,and pump the pedal until it goes hard,Hold your foot on the pedal,does it stay at the top and not drop ,if it drops under your foot pressure then check for leaks,,,i know you say your level is correct ,have you placed a light in the reservoir to check as some times its hard to see through the sides of the reservoir and it looks ok,,to check your servo,start the car with your foot on the pedal,you should feel it drop,this is the vacuum in side the servo ,does it now go down ,pump the pedal it should now go hard again ,stop pumping take your foot off ,press the brake again the servo should build the vacuum back up and your pedal goes down slightly,,,iF these tests pass ok then it would point to an issue with the abs unit (the part that carries the fluid )Inside are solenoids that hold the fluid and these are allowing the fluid to pass over them ,,,

Re: Megane III Brakes Problem

I am currently experiencing a similar problem. Was experiencing soft pedal, brought the car in for a service. My mechanic of many years standing diagnosed worn rear discs. That plus the service cost 510, two days later soft pedal again. Gallic shrug from mechanic. Next visit to maindealer, 70 for a diagnostic. Their conclusion air in rear caliphers. System bled. Another 2 days soft pedal again. Reported same to maindealer, return visit for second diagnostic booked. In the meantime did a bit of research on the symptoms. No leaks apparent, reservoir full etc possible worn mastercylinder suspected. Sought advice from two other experienced independant sources who concurred. Several exchanges of emails with maindealer received two estimates. One for replacent master cylinder costing over 400 to supply and fit. Second worse case scenario faulty Abs pump? Part costing over 500, labour 900 + vat. Car brought in for second diagnostic, result, worse case scenario abs ****ed. To add to the woes I was given the wrong price for the replacement abs parts, it has now doubled. I went back to the maindealer to collect my car only to be told they will not release the car as it is "UNSAFE" to drive. The same car which not two weeks earlier was pronounced fit for use, by the same garage. It has been bumped to head office now because I am being considered a loyal customer (driving only Renault since 1993). I eagerly await the result of That(not). I have to ask the question was it legal for them to prevent me driving away from the garage, other than on a transporter. I had no indication on the dash of an abs fault at any time, and the have completely ruled out the master cylinder. Someone pass the vaseline.

Re: Megane III Brakes Problem

It is legal to stop you driving an unsafe vehicle on the road so yes to that,, it can be transported away, they can not stop you doing that,

Was this the same garage that said your braking system was ok , though it went in for this fault, could have some come back there,
Hope one of the legal eagles on here,, picks up on this

Thanks 2012, yes its the same garage, and I verified what you said about them stopping me driving the car with my own brief. I am still awaiting the solution from the higher echelons in Renault.

Re: Megane III Brakes Problem

they stop you using the phrase "they have a duty of care to you and others" mainly got to protect themselves as well as you ..fault may have also progressed from first visit
