    E46 Corroded Handbrake Shoe Retaining Pin Location - DIY Repair

    Having had the handbrake retaining pins break through a corroded section of the protection plate then roll around the handbrake making a god awful bump and grind I was left with 2 alternatives.
    To replace the protection plate would have cost upwards of 100 at the garage,(wheel hub removal/refit, wheel bearings and a protection plate) so a cheaper DIY was sought out, fortunately dailydoggy suggested using a pressed washer from a Triumph GT6 costing just 90p +p&p

    I bought these washers from the MG Owners Club item #19 having 4 washers delivered for 5.32,
    also available from Cup Washer - for 120124 at www.rimmerbros.co.uk

    GT6 Washer


    The issue appeared after replacing new brakes, discs and shoes all round and the washers were fitted and the car passed the MOT that month and has since passed another MOT, so good for 18mths and counting.

    And so onto the repair, after jacking up the car remove the rear wheel, brake caliper and brake disc, at this point the old retaining pin fell out on the floor and was bent at near 90 degrees!

    So you'll need to order replacements from BMW, mine were approx 12 for a full axle set of springs and pins, part no.34410410823 (repair kit springs).

    Using a dremmel I expanded the location slot in the washer to suit the pin and trimmed the outer edge to suit the protection plate.

    When locating the retaining pin through the shoe, protection plate and washer you'll probably find an extra pair of hands
    comes in quite useful and a 5mm A/F T-bar Allen key is by far easier to use than a standard Allen (hex) key to push and turn the retaining pin 90deg.

    In pic #1) You can clearly see the corroded area where the retaining pin should locate.



    Pic #2) Shows how to remove the 10mm A/F screw, this should allow you a little more room to access and tidy any burrs on the rear of the protection plate.



    Pic #3) Again shows the lower 10mm A/F screw and other corroded area of the protection plate.



    In pic #4 is the new retaining pin fitted in the GT6 Washer (the washer is actually upside down )



    Pic #5 Shows the washer ground to suit the pressed contour at the rear of a brand new protection plate.



    Pic #6 Is the washer and retaining pin as it should look when correctly refitted.



    Pic #7 Washer and retaining pin in situ on the corroded plate and holding the handbrake shoes in position.



    Pic #8 Lower washer and pin in situ , as you can see there's not a lot of room here.



    Pic #9 And finally back together

    Those same washers are used on Rover Metros and 100s too, one of the most infuriating parts of the job trying to get them onto the end of pin!

    Good Mod guys

    They were the old ones that DD removed from his own car when he did his overhaul on his handbrake - @simonsays replaced his and then offered his old ones up for refurbishment IIRC.... Hopefully he will confirm.

    Exactly that @Kevin, I received dd's old/refurbed actuators, fitted them and my old ones were then cleaned, hammmerited and subsequently sent on to another member

    Hello,

    not sure if you will still get this, i know your post ref the back plate on the bmw is rather old.

    I have the same issue where my back plate has corroded meaning the rear drivers side handbrake doesnt work at present.

    I want to try the fix using the washer method however, when i view your post i can not see the photos that you uploaded and feel i need to see these in order to do the job. I am unsure exactly where the washers go??

    I hope you receive this and can help.

    many thanks

    calvin

    Most how to guides refer to having to file the washers hole

    Pin for BMW E36 on the right.

    Pin, for comparison only (and washer) from Mintex MBA642 / BSF0642 (Brakes International)

    As usual, health and safety first, I recommend nothing

    : Just to add the fitting kit is from a transit, so the washers are maybe available separately from ford for less than the whole kit.
