The Wandering bite point can be fixed by a good gravity bleed and a thorough tap the entire length of the hose starting at the calliper or a pressure bleed using modified SRAM Pro bleed kit syringes. Also a hybrid system of XTR Race (non servo-wave) lever units attached to your favourite callipers (or the one that suits your budget) and a proper bleed means farewell to wandering bite point and servo-wave (yaah - Shimano brakes that do exactly what I intended with my finger pull) forever.
Regarding pad noise, a small piece of 3M 2228 tape (which has a high heat tolerance) or the furry side of the velco tape on both sides of the calliper, running under where the fins sit, means no rattle and no engagement noise.
The final brake upgrade that everyone on a 140 mm + bike (or large riders) should try is to get rid of their 1.6-1.8 mm 'XC race weight weenie inspired' brake rotors and install some 2.1 - 2.3 mm 'suitable for real riding' brake rotors (I like the new TRP R1 rotors which are well priced and quiet in use) and run the same size rotor on the rear as the front (see recent enduro-mtb article regarding rear brake heat due to drag, low constant use versus less frequent hard use of the front). As a 98 kg rider it is now 200/ 203 mm for life front and rear.
Happy trails
