Citroen C4 - Hard braking pedal on startup

Post by lancia58 »

Hi

Car is Citroen a petrol C4 1.6 with auto gearbox ( AL4)

Some updates to the following thread

http://www.frenchcarforum.co.uk/forum/v ... =3&t=55836


I noticed that after the car has sat for couple of hours on startup ( after turning the engine on ) the brake pedal is hard when engaging the gear to Drive. On the N position the brake pedal is OK. Before engaging to Drive I pressed and depressed the brake pedal couple of times , but the hard brake is there when engaging the Drive. The brake pedal is back to normal ( almost ) after driving for a couple of meters ( around 10 meters ).

If I tried to get on a high ( 20 cm ) pavement carb the car fails to do it and the pedal brake becomes rock hard.

Referring to my previous thread , the garage suggested to replace all of the valves hydraulic lifters , but I don't think it will help.


Thanks
Zohar
