Hi all
Does anyone have any tips for bleeding the brakes on this model? We've done the normal brake pressure sensor repair in the pump and now cant get a good pedal.
Done a few of these in the past and always bled them at the pump first and got a good pedal straight away.
unfortunately the tech that did this one hadn't done one before and tried to bleed the brakes with a normal bleed procedure.
We have since bled them with diag equipment many times and also at the pump but still cant get good pedal.
Ant tips appreciated
thanks

Sean,
we had a golf in for master cylinder change after the owner changed the rear brake calipers and it took about 20ltrs of fluid and plenty of patients but eventually got there.
I used a combination of pressure bleeder and bosch KTS, kept running through bleed procedure until eventually I got a good pedal. Allowed time for abs pump to cool down.
So it maybe just a case of trying and re-trying unless its a fault with abs unit.
Good luck and buy plenty of brake fluid.

The rear calipers can collect air which can't be discharged by releasing the bleeders and bleeding conventionally.
The trick is to remove the rear calipers, wind the pistons back with the bleed nipple released, then bleed the brakes while tilting the caliper so the bleed nipple is at the highest point.
Also advisable to do this when replacing the rear calipers - They don't trap air every time, but when they do it's mildly annoying stripping again to do what you know you should have done after being bitten once before by this exceptional design.
This is a known issue with Golf 5/6 based variants.
This is assuming you've attempted all known options with diag equipment etc.
When replacing the teves MK60 unit, if you clamp the pedal in position after pressing until pressure is just felt & pop bleed nipple rubbers over the pipes as you remove them, minimum bleeding time is necessary and sanity is conserved.
EDIT we don't send these for repair, we just buy the repair kit direct from TPS, the new units are pre filled and less susceptible to bleeding issues.
