As tony wrote, the fronts are very simple as they use a fixed calipher. So you just tap out the retaining pins and pull the pads from the top.

Push back the pistons and put in new ones.

The rear ones are little more work, but still not very much. You also need to remove a retaining pin, after which you can remove the front pad by tapping it downwards/sideways.

To remove the other pad you can either remove the brake disc (one small screw) or unbolt 1 side of the calipher and 'flip' it up.

The piston, however, can not be pushed back like on the front ones. These caliphers have the handbrake mechanism combined, so you need to push *and* turn the piston clockwise to 'screw' it back into the calipher housing.

It's not a big job, but a little more involved than the fronts.

Also, does the Fed Elise still have the easily-accessible brake bleeder valves? I plan on getting "speed-bleeders" right away.
Should be no different. I use a Motive powerbleeder and that work fine for me.

The fed-Elise probably has the same 'issue' with the front caliphers though.

The inside piston feeds the outside one through a pipe at the bottom. If air is in the system (and this is the only problem.. no issue with just flushing brakefluid to replace it) then you can not 'flush' the air out, because it gets trapped in the inside piston.

To clear it you have to unbolt the calipher, hold it upside-down, bleed (pushing the bubbles to the outside piston as the pipe is now at the top), turn it 'right side up' again and finish bleeding.

The 'off the shelf' AP-racing caliphers have twin bleed nipples for this purpose.. One for the outside and one for the inside piston. But the Lotus/AP-Racing version only has 1..

Bye, Arno.
