udluftning af bremser hj45
hej alle
Jeg har nogle store problemer med at få udluftet mine bagerste bremsecylindere! Jeg har vel snart kørt 4 liter bremsevæske igennem hele systemet - tilgengæld har konen fået trænet hendes baller og ben
Hvis jeg sætter en klemme på bremseslangen før "fordeleren" på bagakslen, så virker det til at der er tryk uden at pedalen skal pumpes en gang før tryk!
What to do?
Er der ikke andre, der har haft problemer med dette?

hmm
måske dette er problemet!
Disc/Drum Double Pump Pedal Finally Solved
Once again I'd like to thank the memebers for all there help. I just got done going thru a few weeks of brake repair that started out with the front discs locking up. This lead into flushing of the lines and replacement of the master, booster and wheel cyclinders and brake lines. I believe that the brake lock up was do to crude in the brake fluid and the residual valve not relieving the pressure. After replacing all the components mentioned, I tried for a couple weeks to get a hard pedal with no luck. After isolating one item at a time it ended up being the rear wheel cylinders. The wheel cyclinders I purchased were the economy models from CCOT since I plan on restoring the truck in the future. After weeks of bleeding and adjusting brake shoes, the culprit was air that was trapped in the rear cylinders. This air trapped in the rear cylinder gave you a pedal that would pump up. I myself thought that air would make the pedal soft all the time and not pump up, but not so. Awhile back Mud member hamm made me aware of a problem with CCOT cylinders and bleeding the air out of them. The method that we used was to remove the caps off the rear cyclinders and push down the piston with a large c clamp vise grip to bleed the air out the tapped holes that are located below the high point of the wheel cylinder. This was done while pressure bleeding and bleeding thru the bleeder screws. This method did not work. It wasn't till member 65swb45 offered the method of disassembling the cylinder, removing the rubber seal and inserting it into the cylinder in the vertical position and then rotating it horizontal while being submerged in the fluid. While performing this you must have the drum on the opposite side of the truck and a clamp on the other wheel cylinder that you are trying to bleed. This is for you don't push the piston out of the other wheel cylinder as your working on the current one. While assembling the cap you want to be bleeding thru the bleeder screw to displace the fluid while inserting the cap into the cylinder. The CCOT cylinders are definetly different from the stock ones that were removed off the truck , The stock ones have a metal cap that has the seal on top of it as the ccot basically has a spring with just a rubber seal that causes a larger area to catch air. The absence of this cap may be the reason why the CCOT cylinders were such a pita to bleed. If it wasn't for 65swb45 and my mechanic's thrive to not let the drum brakes get the better of him, I don't think this problem would have been solved. Some may say that normal bleeding should have taken care of this problem, but not so. This system was pump blead, vacuum blead and pressure blead several times. I hope this may help others with the same ongoing problem.

Re: udluftning af bremser hj45
Hvis det er slik med ccot-sylindere, så høres det ut som et gjentagende problem. F.eks når du er langt fra et verksted eller egen garasje. Finnes det ikke andre hjulsylindere?

Re: udluftning af bremser hj45
Hva med lastesylinderen da?
Har du den ennå?
Den har laget trøbbel for mange før deg....
Og dette er et ganske kjent problem på slike biler.

Re: udluftning af bremser hj45
jeg ville spare lidt penge og købte hos megastore.pt. Men jeg har faktisk været lidt skuffet over delene og kvaliteten af stumperne. Desuden har de sendt noget forkert også.
Men jeg har luftet ud igen i dag og det lykkedes at få mere luft ud af cylinderne. Der er stadig mere, jeg kan pumpe pedalen ca. 1-2 cm inden det maksimale tryk opnåes. Men nu skal bremserne have en lille pause
Jeg har ingen lastventil, så den er der vist ikke problemer med

Nei da kan jeg desverre ikke hjelpe deg Jesper.
Kan det ha kommet noe rusk i bremsevæsken som har satt seg et sted?

Re: udluftning af bremser hj45
Jeg havde samme problem på den sorte, der kan godt stå en lille luftlomme i øverste hjulcylinder, da udluftningsskruen ikke sidder optimalt på disse, jeg løftede bagenden af bilen op (med trucken) til kofangeren foran rørte jorden, da kom der lidt luft ud, og så var det iorden, tror vi talte om det for længe siden faktisk?.. Prøv det hvis du har mulighed for det
Nej jeg har ikke ødelagt den! kun modificeret den udover tolerancerne

Re: udluftning af bremser hj45
ja, vi talte om det, men jeg har ikke muligheden for at hæve den nok, hvis det er der luften gemmer sig! Men jeg har en plan, når den skal ud at rulle på vejen

Her er det utspekulerte og spektakulære løsninger kan jeg lese.
