110_USA Posted March 6, 2008 Share Posted March 6, 2008 Looking to replace both front break calipers on my 83' 110. The old ones are "ab" brand and the numbers are 3247 682C and 3247 681C what is a suitable replacement, as well as pads to go with them? And just out of curiosity why are some $500 or more and can 90 breaks work on a 110? Thank you. Quote Link to comment Share on other sites More sharing options...

Calipers should be AEU2537/8 as far as I can tell assuming it is original, which does not match any 90. Now....keep in mind people change things on these vehicles and that might not be what is on there. These are the non-vented ones. Craddocks prices are 60 and 75 UKP, so around $270 USD for both. Pads are $20. Quote Link to comment Share on other sites More sharing options...
110_USA Posted March 6, 2008 Author Share Posted March 6, 2008 Haha, I tried a play on words because they did indeed break. Thanks for the info. Quote Link to comment Share on other sites More sharing options...
Lars L Posted March 6, 2008 Share Posted March 6, 2008 An easy way to see what brakes you have is that the older version (the part Nos stated by Red90) secure the pads with large cotter pins. Later versions use solid pins with a little spring at the end to keep them in place. Quote Link to comment Share on other sites More sharing options...

JimAttrill Posted March 7, 2008 Share Posted March 7, 2008 If you are going to buy new disks and calipers you may as well upgrade to the ventilated type as fitted to Defenders from 1994 onwards. This is a common modification for Disco Is, older 110s and 90s. They bolt straight on, no trouble at all. Quote Link to comment Share on other sites More sharing options...
Bull Bar Cowboy Posted March 7, 2008 Share Posted March 7, 2008 If the calipers are just corroded but the casting is phyically OK, then a far better option is to rebuild them using stainless steel pistons. The piston corrosion is often restricted to just the chrome on the OEM pistons, very often the caliper bores are fine. This is a cheaper option than replacing the whole caliper........and a very easy job to do.......... Once rebuilt with S/S pistons you can forget about them forever....................

FridgeFreezer Posted March 7, 2008 Share Posted March 7, 2008 Oh and I think you'll find it's AP calipers not AB. Quote Link to comment Share on other sites More sharing options...
110_USA Posted March 7, 2008 Author Share Posted March 7, 2008 Ahh... AP indeed. I'll take them apart and see if rebuilding will work. Thanks for the help everyone. Quote Link to comment Share on other sites More sharing options...
Lars L Posted March 7, 2008 Share Posted March 7, 2008 Err, no. You should not take them apart, as in split the two halves, according to all repair manuals. If that was what you meant? Then, a lot of people have done it and also got away with it. But there is no need, you can get the pistons out anyway. Release the pistons while the calipers still are on the truck. Take out one of the pads and put in some piece of packing like a piece of flat iron maybe 4 mm thick. Then push on the pedal so the pistons go out. Then take the other pad out, put a new piece of flat iron on that side and push the pedal again. Then repeat on the other side, but waht you do, don't remove the iron plates on the first side! The idea is to keep the pistons in their bores, but not releasing them completely. If only one escapes, you'll have to use some other method.

western Posted March 7, 2008 Share Posted March 7, 2008 If you do split the calipers you will need new fliud seals LR part number 17H8764L, IIRC these either 2 or 4 in each assembled caliper. Quote Link to comment Share on other sites More sharing options...
110_USA Posted March 7, 2008 Author Share Posted March 7, 2008 Wonderful info. Thank you very much. I don't plan to split them in half. Quote Link to comment Share on other sites More sharing options...
