Invariably due to a partially seized pad or piston on the OSF
I find this the most interesting post in days. If I understand this correctly, partially seized as in not pushing onto the disc properly OR seized and worn down as it presses against the disc so gets hot and loses performance so brakes pull to the left?
IME, a car does not pull to one side because the brake on that side is working 'too well'...
In this instance, with a multi-pot caliper, the chances are that one piston is 'sticky' and a pad is therefore not being pressed squarely to the disc.

Calipers are use em or loose em items Daz 
in other words dont use em often and things deteriorate pads sticking in guides pistons sticking in bores due to corrosion 
these fancy calipers usually have poor moisture/dirt defense not helped by alloy bodies that s
t when they see rock salt 
IME unlike OE quality main stream calipers

Should have gone for the E38 BMW Brembo 's in other words dont use em often and things deteriorate pads sticking in guides pistons sticking in bores due to corrosion these fancy calipers usually have poor moisture/dirt defense not helped by alloy bodies that st when they see rock salt IME unlike OE quality main stream calipers rigga said:

Yep agreed 
because they was designed for the road and have decent protection boots on the pistons, Metro and Princess 4 pot calipers had a similar design dust seal as many of these so called Go-Faster brake calipers AP Racing/WMS etc etc and they was prone to stick and piston pitting rusting also , for the same reason motorcycle brake calipers need regular maintenance its expected but that's no biggie being a motorcycle TwinKam said:
Oh thanks very much for that. I had just about managed to expunge all memory of those dreadful cars and their nightmare calipers.... and now I won't sleep properly for another 30 years.... great! 
You dig it the most , think last of the original Mini wore those 4 pots too IIRC and trust me I also try to forget the bloody things apart from the P6 and stag I am a Austin Rover/Leyland hater , i'll start talking floors valences and subrames & rear radius arms next

I dont think they will fit inside 16" wheels .AP are good quality and used on theT cars .
AP are a recognized brand, but with the caveats highlighted above
