Tangoman Posted November 13, 2006 Share Posted November 13, 2006 Am rebuilding my brakes and adding gwyn lewis brake linnings he advised me to put a smear of grease on the linnings before fitting them. I would like to hear your views on this please. Quote Link to comment Share on other sites More sharing options...
SiWhite Posted November 13, 2006 Share Posted November 13, 2006 I've heard of this as a recommendation - I'm not sure why it is recommended. Some have said it is to retain the ball bearings as the brake is reassembled. Others have said it is to remove the judder as the brake starts to operate. Seems to me that greasing a friction lining of any type is not a great idea - it will reduce the effectiveness of the lining, which negates the point of fitting the larger linings IMHO.

JST Posted November 13, 2006 Share Posted November 13, 2006 expect TC will have a view, didnt Jay do this and suffer with slipping there after. as Si says i think its to hold the ball bearings in place, Nick have fun putting keeping that circlip on the end, turn into a nightmare on mine after upgrading the pads when the old ones disintergrated. although if you have the older setup without the shims or upgraded or drilled shaft it wont be an issue. mine let go three times after rebuilding it, not nice!

Mo Murphy Posted November 13, 2006 Share Posted November 13, 2006 Nick, can you not ask Gwyn why ? James, did you do his mod with the three bolts on the disc ? I'm curious to find out how people get on with this mod. Cheers Mo Quote Link to comment Share on other sites More sharing options...
JST Posted November 13, 2006 Share Posted November 13, 2006 Mo - No (although Mark 90 has this mod) TC did mine for me (i was late back and was meant to be doing it!!!!) fitted hardend shaft from Giggle pin takes out the sideways float therefore making the brake more efficient as no slack to take up and also has a predrilled and tapped end for an allen bolt so no more circlips for me.

Plenty of 'bikes and stuff are designed with wet clutches - I think some machinery even has wet brakes. You have to use the right oil and, I suspect, the right friction material too.

gsr341 Posted November 13, 2006 Share Posted November 13, 2006 like some one said best thing to do is ring Gwyn , he would be more than please to tell you his views i was down there last week and bought his uprated pads as his pads are bigger (more surface area) any small lubricating effect of the grease wount be noticed over the original pads , as already said , the greases biggest use is to hold and lube the bearings and to stop the dreaded judder as for his mod , it is something he has tested him self , if he wasnt happy it was any good he wouldnt have bothered letting it out by the way i in no way work for gwyn just very happy with his products and service Quote Link to comment Share on other sites More sharing options...
gwyn lewis Posted November 13, 2006 Share Posted November 13, 2006 Rebuilding your 8274 brake asembly with grease serves these purposes in my opinion Puting grease around where the 21 balls sit in help hold them in when reassembly the same for the linings smearing some grease on them helps hold them in place and stops everything falling on the floor When reassembled you should try it out You should get less brake chatter and vibration which is a great help when lowering out and your centre brake disc runs smother when not under load The grease also stops the linings sticking to the metal discs and rusting together after being stood for sometime When i used to compete i used to oil my linings before and after an event to keep on top of this problem I thinck if you filled your brake housing full of grease it might cause pore braking intill its flung out the brake aficiancy of the 8274 is quite good because the brake shaft turns a lot faster than the drum which meansless braking force needed The brake linings i sell are grease and oil compatible and are made out of a more flexible meterial I also recomend fastening in the circlip to stop it spreading owpen and poping of once you have disturbed the circlip they do like to pop of and thats not nice hope this will answer youe questions gwyn Quote Link to comment Share on other sites More sharing options...
gwyn lewis Posted November 13, 2006 Share Posted November 13, 2006 I forgot to mention there are 2 types of circlip sises the older 8274 use a larger circlip 1 nich shaft size the newer 8274 uses a slightly smaller circlip 25 mm shaft sise whith the 3 bellvue washers if you use the older (larger) circlip on the newer shaft it will definetly pop off some people selling the parts do get these mixed up gwyn Quote Link to comment Share on other sites More sharing options...

I'm curious to find out how people get on with this mod. Cheers Mo Mo, I have spoken to Gwyn today and know why but am just interested in people's views, Will report back to you in a couple of weeks on the three bolt mod to hold the circlip on as am fitting this week.

Mark90 Posted November 13, 2006 Share Posted November 13, 2006 I've fitted Gwyn's uprated pads and applied some grease to them when fitting, although I think maybe not enough as I'm still suffering with then sticking to the metal discs when not used for a while. I also done the three bolt mod and have not had a problem with the circlip popping off. Quote Link to comment Share on other sites More sharing options...
Mark Posted November 13, 2006 Share Posted November 13, 2006 I have had loads of problems with the circlip coming off on the 8074, so thought I would give the 3 bolt modification a try (very similar brake mechanism). Sadly, I haven't had a chance to use it since I did the mod, but I will report back on the results.... Quote Link to comment Share on other sites More sharing options...
D9OSV Posted November 14, 2006 Share Posted November 14, 2006 If you fit the circlip the correct way..... You should not have any problems, the correct way is with the rounded edges facing the brake. As for greasing your brake......... You'll find that the Welsh are well ahead of us when it comes to lubricating anything........ Something about no foreplay.....

white90 Posted November 14, 2006 Share Posted November 14, 2006 cir clip flying off agreed not nice and time consuming looking for lost bits in the dirt I greased the pads but I fitted the Main shaft from Jim http://www.gigglepin4x4.net/8274/mainshaft.htm this singularly made the winch quieter in operation and gave me more confidence in it being lowered out over long drops etc etc. The circlip is so 20th century to quote Jonny boy Quote Link to comment Share on other sites More sharing options...
will_warne Posted November 14, 2006 Share Posted November 14, 2006 Gwyn, is there a specific oil tou reccomend? I was thinking about using a marine grease with mine as the brakes aren't exactly waterproof Re oil filled brakes, I'm told at fully sealed systems are quite common in agricultural and industrial machinery and I assume they're oil filled. Also look at an auto 'box, they use oiled clutch packs. Quote Link to comment Share on other sites More sharing options...
D9OSV Posted November 14, 2006 Share Posted November 14, 2006 Will, your missing the point, Any lubrication is considered better than none. Any oil or grease for that matter will suffice, However i'm sure if you want to get into it that some work better than others........ That is until you add a bit of peatbog, some sand, large quanities of water and some clay...... And pretty much anything else you drive through Jim Quote Link to comment Share on other sites More sharing options...
Adrian Turner Posted November 14, 2006 Share Posted November 14, 2006 Jim Ps: The Twinmotors are coming......

gwyn lewis Posted November 15, 2006 Share Posted November 15, 2006 Will The grease i use is morris K48, the same grease we supply whith our propshafts and the same as you should be using whith h/duty c/vs and wheel bearings It is a molybdenum disulphide product whitch means when all the grease looks to have flung out you still have some lubricant left, when you get it on your hands you will see what i mean you wont know what youve mised intill you have tried it you can check it out www.morrislubricants.co.uk search for k48 gwyn Quote Link to comment Share on other sites More sharing options...
white90 Posted November 16, 2006 Share Posted November 16, 2006 Thanks Gwyn for explaining. does the grease come in tubes for a grease gun? if so what sort of ££ are they please. Quote Link to comment Share on other sites More sharing options...
will_warne Posted November 16, 2006 Share Posted November 16, 2006 Thanks Gwyn for explaining.does the grease come in tubes for a grease gun? if so what sort of ££ are they please. Not sure, Tony, although I've seen it in big tubs for industrial grease guns. Quote Link to comment Share on other sites More sharing options...
Bull Bar Cowboy Posted November 16, 2006 Share Posted November 16, 2006 Thanks Gwyn for explaining.does the grease come in tubes for a grease gun? if so what sort of ££ are they please. Tony, Yes, it is widely available in grease gun refill type tubes………….For years I have used nothing but moly grease in all components ………… like Glyn was implying, it sticks like sh1te to a blanket and even after you have wiped it off it leaves a film of lubricant. If used to be more than twice the price of general lithioum grease but these days its probably only 10 or 20% more expensive, but IMHO worth every penny. For years the Race Car grease monkeys always used to refer to it as ‘Black Magic’ I normally buy either Comma, or Shell Moly CV grease in 1 Kilo tubs as both my 8K psi Tecalimet grease guns are manual fill. …………. Partco, AutoQuip, Kevin Cooper, ALS etc…… will all stock them. Now............ if you had a hydraulic winch the brake and all its complexity is not required as we get no run on or winch creep Ian Quote Link to comment Share on other sites More sharing options...
