Tractorboy16 Posted February 8, 2009 Share Posted February 8, 2009 Hi, can you put defender calipers on range rover axles, running range axles on hybrid but defender brakes so was wondering if i could fit defender calipers on the front axle so then i could use a defender set up. Any help much appreciated. what i have at the mo!!! James Quote Link to comment Share on other sites More sharing options...
western Posted February 8, 2009 Share Posted February 8, 2009 provided the caliper attachments line up with the axle, I can't see any reason why you shouldn't fit 90 or 110 calipers. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted February 8, 2009 Share Posted February 8, 2009 Be VERY careful. Depending on the age of your respective axles and calipers you may find that the caliper bolts are very slightly different diameters. The bolts are an interference fit in the caliper so even a slight difference in diameter will allow the caliper to move under braking loads. Why do you not want to use the RR calipers?

dirtydiesel Posted February 8, 2009 Share Posted February 8, 2009 You probably want to go with 110 ones over 90 callipers, as 110 callipers are a lot bigger, the 110 pads are about 50% bigger than 90 ones. Quote Link to comment Share on other sites More sharing options...

lrfarmer Posted February 8, 2009 Share Posted February 8, 2009 i fitted my 90 brake calipers to my disco axles my brakes are purfect like it but i did find that i needed to make new brake pipe brakets on axle. as the 90 once pointed the wrong way when fitted on the disco axle.

James A ha! Exactly the problem I faced. Ended up sticking with the Defender axle. Quote Link to comment Share on other sites More sharing options...

From the Defender 1991 model year onwards the braking system components were rationlised across the Defender vehicle range, so parts like calipers/disc/servo's were common to assist production.

max-ie Posted February 8, 2009 Share Posted February 8, 2009 Hi, This\ is interesting as i'm just \in the middle of plumbing a 1985 90 setup to Rangerover axles and callipers. I've simply made the twin circuit callipers into single circuit with the use of a two into one T junction..Then running single pipe to the master cylinder via a second T junction that runs to the other front Calliper. The rear circuit runs via the distribution valve to the rear single curcuit callipers at the rear. I can't see why this would not work. How have you plumbed yours. It looks a bit more complicated in the first photo. Quote Link to comment Share on other sites More sharing options...

Hi Max-ie, interested in your system, just to clarrify, is this what you have done, little diagram!!! you have put t-pieces on both front callipers to make single circuits and then T-pieced these together so you have a single front system for the front brakes, are you running this circuit of the nearest to bulkhead outlet on master cylender or furthest one away? and then running a second circuit to the rear vier a ditribution valve? see diagram if it works!!! have you tried this yet? or still building it? Many thanks James Quote Link to comment Share on other sites More sharing options...
max-ie Posted February 9, 2009 Share Posted February 9, 2009 Hi James, yes this is how i've done it. The primary circuit is the one furthest from the bulkhead. This goes to to a T then off to each front caliper. The secondary circuit (rearmost to bulkhead, goes in the side of the distribution valve. A pipe then comes out of the front of the valve turns 180 and goes to the rear axle. Id initially got this the wrong way round. I've not got any braided hoses yet, still saving so don't know if it works. I was reading today that the system should be left open to allow the free flow of fluid for 5 minutes prior to bleeding. I suppose this is so all the pipes get filled before the bleeding process. I can't see any reason why this would not work other than a buggered valve in the\master cylinder. Letr me know if its ok. I'm sending for some parts at the end of the week so you will get there before me. Max Quote Link to comment Share on other sites More sharing options...
Tractorboy16 Posted February 10, 2009 Author Share Posted February 10, 2009 hi, no worries, sounds good, i shall have a go, not sure il get it done this week either as fairly busy but shall get on as soon as i can, need to get a new distribution valve as well, you using a standard range rover/ called pressure valve i believe? Many thanks James Quote Link to comment Share on other sites More sharing options...
