Pete Lewis Posted April 22, 2017 Report Share Posted April 22, 2017 Not happy with the handbrake on my 2000 mk2 on examining the rear brake its common to many cars of the 70s with expander and ratchet cam auto adjusters the main wear is in the cable lever pivot , repaleds that with a shanked bolt , but there is a wear point where the lever rubs on the shoe webb , so a bit more of a search required heres a usefull site with all the old brake catelogues ....but no expanders are listed by lockheed Odd that !! http://www.northwestclassic.co.uk/ this is the expander used on lots of UK built cars on the vintage well supply of 518681/2 for the saloon is rocking horse pooh supply for Stag 519070 /1 is available in volume different part numbers normally mean different parts ....it seems on the face of it not so.. im not stripping her down till we have finished drive it day, but research the variety of photos online supplies show the Lockheed numbers , for each part of the lever, yes Stag brakes are different in a number of small upgrades and sizes ...but unless someone has used generic photo's the Numbers on both 2000/stag levers show as the same ,, so by early next week i will have the old refettled off for a dimensional comparison this may be a simple mistake by suppliers photo shoot or a gross cock up in missed opportunity next week will give me the answer ,, put up or shut up Ha ! edit just to add the self adjust ratchet cams work fine ,, no problems there.

sulzerman Posted April 23, 2017 Report Share Posted April 23, 2017 Hi Pete I recently purchased a near side brake expander for my 2500 from mick dolphin. Don't know how many he has. May be worth giving him a call. Cheers Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 23, 2017 Author Report Share Posted April 23, 2017 Yes thanks , I looked at mick earlier but none listed Whilst theres not much wrong with what I have fitted im on the case of the the lockheed identification numbers and check the stag with with the saloon ones dog with a bone syndrome . Do you have your old one ?? what number's are stamped into the levers ??? pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 2, 2017 Author Report Share Posted May 2, 2017 right the plot is solved , the levers on 2000/2500 are expander spreader bar 35654410/11 for rh and lh SAME AS STAG the handbrake pivoting lever is 3626 655X on 2000 and 3626 662K on Stag, the difference being the Stag lever is 15mm longer to the clevis hole giving more mechanical advantage so advantage to all 2000/2500 is to fit the cheaper and available Stag expander part number 519070/71 which will improve handbrake applied effort to the shoes . so why has the supplier trade not work this out ?????? its not rocket science Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 2, 2017 Report Share Posted May 2, 2017 Well no, it's not rocket science, rockets don't have handbrakes . Link to comment Share on other sites More sharing options...

Pete Lewis Posted May 3, 2017 Author Report Share Posted May 3, 2017 Well they are in fitted and perfect To remove /refit the bar its tight btween wheel cyl and hub flange , undo the 6 back plate nuts and pull hub fwd a few mm lets the bar slip inside this would also be tight with the normal 2000 unit as the spreader bar is identical the longer crank levers for the cable fit fine , just needed small cable adjustment 6 clicks max at the handbrake and its fine she was fitted with non asbestos cardboard linings a year ago they look awfully orrible black and grotty they are in the bin and the old proper ones refited if anyone had concerns about the cable lever being 15mm longer its unfounded and you could drill a clevis hole to replecate the shorter and pick a long or short option well chuffed with the idea and the result pete Link to comment Share on other sites More sharing options...
sulzerman Posted May 8, 2017 Report Share Posted May 8, 2017 Hi Pete Sorry couldn't find original expander I must have thrown it away!! Sounds like the stag parts are a good conversion Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 9, 2017 Author Report Share Posted May 9, 2017 Thanks for looking , The orig linnings make far better braking than the aftermarket which were from club shop Ex brake engineering , you could apply the foot or hand brake and still turn the wheels just no friction and the more you cleaned and re tested the black dusty grime appeared on the brake linning surface putting the old OE spec back on and jimminy cricket one heck of a difference so with stag spreaders and old linings you can tell you have some ground anchors at the back end MOT at 9 today that should prove out some better figures than the raised eyebrows from last year its been an interesting excercise pete Link to comment Share on other sites More sharing options...
sulzerman Posted May 9, 2017 Report Share Posted May 9, 2017 Pete I may have to invest, as my handbrake after many hours of adjusting is still rubbish Thanks for the info Cheers Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 9, 2017 Author Report Share Posted May 9, 2017 You need to make sure the expander is operating the ratchet cams that lock the shoe in its fully adjusted position , the age old thing is the cable lever gets siezed on its pivot. if you whip a drum off and gently press pedal you can hear the ratchet click up the cam easy to de adjust by lifting the sprung upper ratchet cam out of mesh. the car leapt out the rollers on handbrake rollers at todays MOT, if the adjuster cam ratchets have worn and dont grip the kit is vastly expensive for what it is if the cable is pulling the adjuster and opening the shoes you will always have a poor foot brake. must get the adjusters to work ok then fit cable pete Link to comment Share on other sites More sharing options...
