    Hi everyone,
    Could do with some advise please.My clk w209 has always had a poor parkbrake,only scraped through last years mot.Time to sort it out.I stripped rear end to find pitted and corroded shoes and drums. Ordered parts fitted them this morning with no real drama's.Slacked adjuster on compensator first,fitted new rear disc/drum and shoe's both sides,adjusted shoes rebuilt and adjusted compensator.

    PARK BRAKE STILL AS RUBBISH AS BEFORE.......
    Do i have seized cables or am i doing something wrong

    Please advise

    Yes its important to back off the cable first under the seat. When fitting new shoes I tap the drum all round to be sure the shoes are seated evenly, then do the shoes up tight, then hit the drum all round again. Then back off as DB auto says, never back off too much there will always be a slight rubbing sound for a while.

    Then adjust the parking cable again. They are never that good :( as probably too small for the weight of the car.

    By locking them really tight on the adjuster will centralize the shoes, do oil the equalizer and very light oil the levers that pull the shoes on, just a tiny amount

    It all adds up to a lot in the end

    They are just not very good,,, strange as my V70R has the same size drum and you cannot drive with the parking brake on.

    Even the electric version on my CL will not hold my car, strange that MB have got away with it for so long

    I tried my CL216 again today on a tiny slope, and it rolled away so be happy and just use P all the time as I have to
