Smego Posted January 3, 2016 Share Posted January 3, 2016 Hello I have a 1988 110 with the age old issue of every year the hand brake locks on during the wet months, every year the mechanic strips and cleans it and it works again. I cannot afford the obvious answer of an x-brake and not able to make one up from old bits. It is always just caused by crud, getting in the open "seals," not being able to get out, and drying inside, a blow out with the airline, a few degrees with the adjuster and all ok till I can get it apart for a proper clean but it is a lot of hassle. I was wondering as water and crud gets in anyway whether it would be possible to cut a few small slots in the front plate, one at the bottom to allow draining and two at the top edges to allow cleaning (airline) and lubricating. Not sure if this would weaken it all cannot see it as only the front cover and whether it was just a bad idea for another reason, yes it will let more crud in but will be a whole lot easier to get it back out without the juddery drive home to let it dry and get tools?

Smego Posted January 3, 2016 Author Share Posted January 3, 2016 PS I did make a couple of small drain holes at the bottom that I though had worked last year but they are too small so get blocked up. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 3, 2016 Share Posted January 3, 2016 I've seen one with a large hole saw taken to the face of the drum, I guess it worked OK.... Quote Link to comment Share on other sites More sharing options...
simonr Posted January 3, 2016 Share Posted January 3, 2016 Before the X-Brake, I had 4 x 13mm holes (only because it was the biggest drill bit I had) symetrically drilled in the corner between the round & flat faces. It allowed the water to be centrifuged out - but were also big enough to poke a hose pipe in to wash all the mud out of the interior. It worked very well in maintaining the performance - though it has to be said that the performance was never that fantastic, which is what led to making the X-Brake!

Bowie69 Posted January 3, 2016 Share Posted January 3, 2016 As an aside, the drum drills very easily with a sharp bit, so not a lot to lose I guess.. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted January 3, 2016 Share Posted January 3, 2016 As an aside, the drum drills very easily with a sharp bit, so not a lot to lose I guess.. There cast iron so as long as your not using to high an rpm your drills will drill it for ever and a day. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted January 3, 2016 Share Posted January 3, 2016 The td5 style hand brake is much better it uses levers instead of a tappered pin and rollers you can pick them up for around £40 second hand. Mike Quote Link to comment Share on other sites More sharing options...

honitonhobbit Posted April 27, 2016 Share Posted April 27, 2016 The RRC version from '86 to 92 is quite good - not as good as the Td5 one Might I also suggest that when your mechanic strips it down again - get him to replace the internal springs - they are pennies, come in packs of 5 and are a nice light blue and/or red colour...
