Drum to disc conversion decision


eds

Recommended Posts

I would like some friendly advise :-) Which option would you choose............

I have been offered what is considered a good quality disc braked Salisbury axle complete for £600 from a later vehicle

Or should I do the Diesel Jim conversion on my current 1993 drum Salisbury axle

Both options would need new callipers and discs.

£600 sounds expensive for an axle, but would the cost outweigh the saving in hassle.

Also confusing is the news that my stubs are better setup with wider spaced bearings. Is this crucial to the decision?

Looking forward to some help. Thank you :-)

It does seem a high price. It is in the same town as me and supposedly grade A and still on the donor vehicle so I could verify that. The bloke selling me it says they are hard to come by these days. It will come with discs and callipers but they do not want to sell me them for health and safety.

Watching that ebay, thanks for the tip.

Western, that is a kind offer, could I buy them? :-) I did not know that an alternative sized spacer is possible, how would I know which to choose?

Yes no probs, have replied to your PM.

these fit between the caliper bracket FTC3306 & the axle flange the stub bolts to.

That's my ebay listing for the bracket. I was going to do the same conversion and started collecting bits, then was persuaded that it would be simpler to just swap in a whole TD5 axle.

In the end, I replaced most of the components on the TD5 axle I bought from a breakers as they were shot. It would have been much cheaper to just convert the existing axle to discs.

I also have a pair of brake discs that I collected and tried to use for the TD5 axle having forgotten that I had bought them for the old Salisbury axle.

Well thanks for the ebay buy it now, had I known you were a forum member I might have been cheekier with my offer!!

Western you have confused me now by bringing in multiple spacer depths. If I am following Diesel Jim's guide then I thought 6mm was clearly the only option. I could not quite understand your link re differing disc sizes. When you did your conversion did you use FTC3846 discs and STC1268 calliper? Do you know why you ended up using 10mm. Will I not know the size until fitting.......

Mike I tried to search through your thread to find the reason you did not use the 6mm spacers but could not find the answer. Could you let me know.

Am I not going to know what spacer to use until I am rebuilding the axle.

What I did read made me think about balanced braking between front and rear, do I need a thing to adjust braking pressure?

copy/paste of bolt info from the longer thread, thread is worth a read. http://forums.lr4x4.com/index.php?showtopic=60726&hl=

"Bolts for the caliper brackets were (per side)

2x 48mm M10 8.8 Set Screw

2x 58-60mm M10 8.8 Set Screw with 2x M10 nyloc 8.8

2x 35mm M10 8.8 Setc Screw with 2x M10 nyloc 8.8

Bought 50mm Bolt and 60mm Bolt but unthreaded portions will not go into axle bracket enough, So needs set screws fully threaded.

The outer edges of the 6mm spacers MUST be flush in line with the radius of the caliper bracket or the disc will foul the radius portion. the inside by the axle tube is not as critical.

RTC 3511 oil seals need to be tapped in gently with another scrap rtc3511, to obtain one first try to fit seal using a block of wood. :blush: which collapses the seal nicely.

The seal inner lip needs to be under the lip by 1mm-the main lip should be recessed by 4-5mm. Don't forget to put the greased wheel bearing in first."

I worked out a complete 110 system to possibly fit to my 109 which does not have any brake balancing involved, you'll find the thread in the part numbers board I think
