brembo caliper

hi, does any one know if the brembo s/c calipers are handed and if so how can you tell left to right, apart from the bleed nipple, but looking at it that could go on top or bottom

I've not seen the RR Brembos up close and live (have them on my Porsche though Razz ) but bleed nipples must always go up - al least they do if you actually want the air out of the system... Rolling Eyes

OK, I think I understand. After doing a number of brake conversions on Porsches - have not felt the urge to on RRs yet (although an emergency stop from 100+MPH as I had on the 'bahn this past week def showed weaknesses in the 2.6t TD6 RR's brakes) - I can say that generally Brembo calipers have 2 criteria determining 'handedness': 1 and the primary being the relation of the smaller piston in 4 or 6 piston calipers to the location of the mounting flange/direction of rotation (smallers always lead) and 2 being the location of fixed bleed nipples. The smaller piston in relation to the mounting flange determines L or R. In calipers with an open line between the caliper halves, bleed nipples can be swapped with the connecting line to compensate for a fore/aft location of the calipers to locate the bleeds up. Fixed bleeds mean a fixed location fore or aft.

ok how about the mounting on the caliper are always inboard to the car so if you hold the caliper to the car on the drivers side and the mountings are at the innermost to the car if the bleep nipples are top its a drivers side but if the nipples are at bottom its a pass side very simple description but should be usefull onto no6 Range Rover

ok, let me start again..i bought a single new brembo calliper from a s/c rangerover, it has the bleed nipple with it but not fitted so it could go at either end, looking at the back it symmetrical they is no differences,i.e bumps, knobs, part numbers of castings so with the bleed nipple not fitted it could go on ether side V8 facelift Range Rover Autobiography 22" wheels.

Don't you have 2 nipples - inside and outside? Brembos are generally not 100% vehicle specific - which means the nips can be mounted either or to adapt to the mounting location.

I've never looked at an S/C steering knuckle, but I'm assuming it retains the aft caliper mounting. So for an aft mount, pretend there's a brake disc in the air in front of you hold the caliper vertically at the rear of the brake disc with the mounting holes/flange towards the inside of the pretend vehicle (away from you). Is the larger set of pistons up? Then your bleed nipples fit to the upper holes. If the smaller pistons are up, you'll have to walk around to the pretend other side of your pretend vehicle and hold the caliper behind the pretend disc there. Rolling Eyes Find the correct location of the caliper and the position of the bleed nipples becomes self-explanatory.

Basically, for aft mount calipers, the bleed nipples go on the side of the larger pistons and for front mount calipers on the side of the smaller.

Why though? What are you planning on doing with one caliper? If this exercise was so that you can look for an appropriate 'other' left or right caliper, be aware that there is much more to a conversion such as this than simply bolting on calipers/discs. Problems start with brake bias (you need to modify the rears and the fronts at the same time), master cylinder/ABS/TC pump volume (it takes a greater volume to move multi-pot calipers than the single-pots on a standard RR). I don't know what other differences LR made to the braking system, but this is something that you would def need to look at before attacking your RR with a wrench (spanner) or even ordering a bunch of parts that will do nothing for you other than blinging your workbench.
