914World.com _ 914World Garage _ Putting old brake pads back in

Posted by: john77 Aug 12 2015, 04:44 PM

I took my driver side rear brake pads out to check if the rotor was warped. If I want to drive the car 'as is' until I have a chance to get them machined, do I need to adjust the pistons for clearance when I put the old pads back in?

Excuse my ignorance on this, it's all completely new to me.

I think it's a always a good idea, or maybe even just plain necessary, to check brake venting clearance after working on the rear brakes. It's not that hard. Here's a good reference:

Okay, now I'm confused, these aren't the same brake calipers as in Eric's article. There's a raised logo that kind of looks similar and P67 stamped on them. Anyone know what they're off?

Those are 911 rear M-Calipers with 10mm spacers and vented rotors. You probably no longer have a handbrake.

Thanks Eric. Nope, no handbrake.

Just pulled my copy of 101 Projects off the shelf to see if that could help and noticed they're exactly the same as the ones in the project...

So the pistons don't need to be messed with to give the pads clearance on these? I checked on my passenger side rear and the pads are flat against the rotor with no clearance at all.
