Hi,
My Berlingo has a lot of pedal travel before the brakes work, the pedal is about 3/4 of the way to the floor which is a bit worrying.
The brakes do work and stop the vehicle well if you hit them but I don't think the pedal should be so low before they work.
I have done a bit of work to try to get the pedal better...
The servo is working as it should so no problems there.
I removed, cleaned and greased all four callipers (discs all round) so they are all sliding nice & freely and working as they should, the pads are all free in the carriers and in good condition as are the discs.
I removed the master cylinder and reservoir to check them over, I stripped the MC and replaced the seals even though the old seals looked fine, the MC is alloy and in good condition, the bore is nice and clean with no damage.
Fitted the MC back on the car and pressure bled the whole system with brand new fluid, so that is all fresh and clean.
(No air to report during bleeding)
With the engine off and the vacuum out of the servo if I pump the brake pedal it holds firm pressure with no real noticeable creep so the MC is holding pressure as it should.
Despite all of my efforts the pedal is still very low just like it was before I started and I don't think it should be like this.
Does anyone have any ideas as to what could be the cause of the low pedal?
Thanks.
