Brakes not working

Post by jyekook »

Hello everyone - Peugeot 308 Hdi 2010

I recently replaced my abs pump and now my brake pedals have zero resistance and are floppy. Could anyone point me in the right direction, what is the cause?

I have bled the brakes twice and bled the ABS pump using a scanner. I am also getting a new fault code - C 1389 brake fluid level too low (the brake fluid is at the correct level on master cylinder.

I also depressurised the brake pedal for a week, while I was changing the abs pump. I don't know if this is related.

Possibilities could include air still in the system or the master cylinder seals are faulty.

Yes, very likely has not been bled properly and in the correct order.

My scan tool says I need to apply to bar of pressure when bleeding abs. I only have a traditional one man bleeder (bottle and tube). Will this still work?

I don't think it will, if they specify a pressure bleeding then it must need it. You can get either Pressure or Vacuum bleeding kits from most car parts stockists.
