Hi

     Just fill us in on a few more details. e.g, have you clamped off the flex hose to see if the problem is one side or both sides or even if there is a problem with both clamped indicating air in master cylinder or ABS unit.

     CAn we assume discs are good, good quality pads fitted, has the car been driven to bed in the pads. how bad is bad?

    I assume That as you have access to a scanner you will have checked most or all of the above already, but let us have the results.

     One unusual problem I had (not on a galaxy) was a slight bend on a calliper guide pin resulting in the calliper not sitting square on the pad. The brake pedal was good with the old pads because they had worn at a taper, but poor with the new pads, check the old pads to see if they are worn square

Hi

    Just check for bleed nipples on the master cylinder, some VW's have them, not sure about the galaxy from memory but worth a look. Can not help ref bleeding with Launch, but think KTS will do it.

i am with aidan on this one

i did a golf a few weeks ago and it had been to two garages before for long travel on the brakes but none had cured it so with a quick bleed of the system including the TWO bleed nipples on the master cylinder it was spot on

hope this sorts you out.

Tim.

If it has no bleeds, just undo the top two pipes (if its a four pipe system) put a cloth under the pipes, Push the pedal to the floor and tighten tyhe pipes.

OR wedge the pedal Down over night, you could be surprised in the morning.Wink

Hi

   good tip of kevs that, we found that worked on transits, often had a poor pedal after fitting pads, left a pedal presser on over dinner time, not sure why it works though.

It leaves the very thin valves on the piston rubbers open and the air floats to the top and into the master cylinder. Or that is the only thing i can think of, but then i,m not that clever anywayHehe

This is not really relevant to this topic but is worth a mention.

We had a Rover a while back that the owner had fitted a set of pads & afterward suffered a spongy pedal. The problem became obvious when the callipers were viewed whilst the pedal was applied. The nearside front calliper was clearly moving more than the offside & the reason was that the "audible wear warning" spring strip on the pad, had been caught the wrong side of the pad mount surface & was pushing the pad away from the disc by about 2mm.

Like I say it's not likely in this situation, but it serves as an example of what silly little things can cause these problems.

Cheers!
