HEMI-V8 Posted March 24, 2015 Report Share Posted March 24, 2015 Hi. Today I started bleeding the brakes with my brother-in-law, after installing these days a new precharged accumulator. Started like its described in the haynes repair manual at the right front brake - all good. Then started bleeding on the right front brake. ( regularly checked the fluid level) But after approximately 15 minutes of bleeding, there is still air in the hose ? What could that be !? Currently Im pretty frusted with the brake problem.

redgrandprix Posted March 24, 2015 Report Share Posted March 24, 2015 (edited) If its a pm3 you have to cycle the key on, let the pump run, turn key back off then push the brake and open bleeder. Also make sure you close the bleed screw before you release the brakes to avoid sucking in air.

HEMI-V8 Posted March 24, 2015 Author Report Share Posted March 24, 2015 Ok. Haynes writes that i must depressure the system by ignition off, pumping 40 times the pedal and than starting bleeding the right front brake. I will test your method and see what happens. Hope all is fine soon. Quote Link to comment Share on other sites More sharing options...

Hope all is fine soon. Front calipers can be bled with the unit off and depressurized. Rear calipers need it running/pressurized. There's also a bleeder on the PM3 itself.

HEMI-V8 Posted March 29, 2015 Author Report Share Posted March 29, 2015 I´ve got an really good manual who decribes all bleeding steps. Currently it seems that the air in the front brakes therefore was air in the PMIII unit. After bleeding that all was fine, till my accumualtor was leak because it was not tight enough in the unit. These days I will bleed again the system. Quote Link to comment Share on other sites More sharing options...
HEMI-V8 Posted April 7, 2015 Author Report Share Posted April 7, 2015 After bleeding the second time, I see now an minimal leak on the accumulator thread. I sealed it with teflon tape, but that seems not to be the best for this. Does anyone knows an good thread sealing compound which is resistant to brake fluid ? I´ve contacted also Loctite but they are not able to answer me. (service wasteland germany once again) Quote Link to comment Share on other sites More sharing options...
