bigger diameter, more pad surface area. More plentiful than MY. The last set of pads I fitted, cheap arse no name I can recall, made a jarring noise on a particular turn, just in front of mates workshop

I kept the front brakes off my impressive braked L Touring Wagon just for this ! Got pads, rotors and hopes the splined hubs too - making room for more junk or Jonno in the parts shed !! Current pads are at the end of their service life. Nice timing ...better get it done and sorted before Xmas break !!
I might be the pic supplier ! Well, no, I won't be, just yet
Just been looking at a pair of L calipers. The calipers are cast and they bolt to a bent pressed metal gold zinc plated bracket via one bolt with 12mm head - the bolt undone to replace brake pads. The other point of contact is the other greased slider ! So, must be the sliders that have a common centre to centre measure and the L caliper slides on to the MY caliper brackets slider pin. Guessing L pads are still used and fit between the gold zinc plated bracket ?
Now, the technical engineer comes out to measure the sum of the fluid in all lines and calipers at maximum pad wear to determine if a larger capacity brake fluid reservoir is required - totally not taking into account the level should be topped up as it drops below max fill line.
Paul states this is with L Series RX front disc rotors, splined hubs and calipers and knows not if plain old L Series stuff works - think it is no different. RX masters were different and interchangeable at same time. Running a normal one in my GLTA
Where was Paul when this big debate was on ???
Sam...you had an L for parts ...sounds like you chucked all the good bits !!
