Barob Posted February 13, 2019 Share Posted February 13, 2019 Hello fellas I have a 1988 Defender 90 which needs the brakes overhauling. I am happy to replace with new parts if not too expensive. Should I replace the front disks with standard disks callipers etc. or take the opportunity upgrade?? Would 110 brakes be better and would they fit. They seem to be cheaper on Paddock spares. Same for rear...is a disc upgrade expensive..worth it?? Cheers Quote Link to comment Share on other sites More sharing options...
Gazzar Posted February 13, 2019 Share Posted February 13, 2019 Were the brakes okay? Originally? Do you do lots of towing heavy trailers? Do you drive a lot in the mountains? If not, keep standard, easier to explain, insure, and if there's an accident, then it's not something you've to worry about. Plus, easier to service in future, as all standard. If you found the brakes poor when in standard form then that's different. Quote Link to comment Share on other sites More sharing options...
western Posted February 13, 2019 Share Posted February 13, 2019 (edited) Post 1991 90 & 110 use the same brake parts, you can change fronts to vented disc/calipers they will help prevent brake fade when towing. sorry read it as 1998 90 Edited February 16, 2019 by western Quote Link to comment Share on other sites More sharing options...

On the wide hubs (pre-300TDI) vented calipers hit the hubs and do not fit without modification. Edited February 13, 2019 by Red90 Quote Link to comment Share on other sites More sharing options...
Barob Posted February 16, 2019 Author Share Posted February 16, 2019 Thanks for replies I don't tow with it so maybe standard will do. I use it for trialling with my local club. Sometimes driving through deep water and I feel this doesn't do the rear hub brakes any good as they stick on after a week or so of standing. Has anyone upgrades to rear discs?

western Posted February 16, 2019 Share Posted February 16, 2019 quickest & easiest way to upgrade a older 90 is to fit a Discovery 200tdi or range rover classic rear axle. on the Disco axle it need the prop flange changing for the one to match your existing rear prop.

Ex Member Posted February 16, 2019 Share Posted February 16, 2019 If you are getting new calipers, get the later ones. This makes it easier to get pads and such in the future and makes sure you are getting the larger pistons. You can fit rear discs. There are a few writeups on the forum on what to do.

Britcyclerider Posted March 10, 2019 Share Posted March 10, 2019 Careful of brake balance if converting rear drums to discs. The bias valve should also be replaced to the type appropriate for rear discs. Quote Link to comment Share on other sites More sharing options...

I have vented front disc brakes on a 1985 90 axle with the original hubs. Mo Quote Link to comment Share on other sites More sharing options...
