D90 and Discovery S1 brake caliper compatibility

People Hi,

a good friend and fellow LR club of Greece member has managed to snap the
front right (driver's side UK) brake caliper from its mounting bracket (the
bolts remained in place on the front axle along with the "ears" of the
brackets)

Since welding the caliper's broken brackets/"ears" is out of the question
due to safety we are considering using a front brake caliper from a
Discovery S1 or Range Rover Classic (non vented type).

I know that Discos and RaRo Classics had a twin brake hose setup but does
anyone know if blocking one of the two brake hose holes will make it
compatible to the single brake system on Defenders?

Take care
Pantelis

The Ra Ro Classic caliper will not be compatible as it has two separate
systems but the Disco 1 is the same and interchangeable as all pistons are
interconnected from the one supply pipe. Some 90s though have bigger
calipers in which case you couldn't use either of the above unless fitted in
pairs and someone also may have retro fitted them but they are physically
bigger and easy to see the difference so do check. I suppose in emergency
you could use a R/R caliper if you fed both systems with a T junction on the
caliper but only as a very temporary measure.

You'd also need to check the bolt centres for fitting to the axle,
they vary, as do the sizes of the bolts.

Richard and Martin thanks for the swift replies.

I guess it will be best to try and find a D90 caliper and be on the safest
side.

Take care and thanks again

both my disco ones have the twin front pipe set up as per the range
rover.

According to Paddocks, both use the same part number for Disco and RR,
which seems to confirm this.
