Hi , Fitting new brake pads to front of my 87 late offset 220 turbo. Old pads came out ok but snagged against the aluminium plates slightly coming out. New ones don't want to go past the plates and I don't want to force anything.

Pistons pushed right back but it's not the pistons that are the problem.

I'm not supposed to remove calipers and then plates to change the pads am I?

Sorry for the stupid questions. Thought they would just drop into place like other cars I've worked on :)
 
What you are describing is known as "plate lift" and is a corrosion problem.

See here for an explanation:

You have the dreaded plate lift! It happens to all turbo and s2 owners at some point! You will need to get the calipers off and get them refurbed. You can file your pads if you want a bodge but not recommended.

You need to get the plates off and remove the corrosion which is "lifting the plates" before re-fitting the plates again. It's not just as easy as that though they are a bugger to get off, probably easiest to weld something onto the old screws and get them off that way (they are locitited in), you will need new screws for re-fitting anyway. Probably also a good idea to service the pistons and seals and paint them while you are at it to complete your refurb. Good luck!

Cheers

Oops, only read this now after having another go. The pads went in with some very gently persuasion and all seems ok. I guess I'll have to look at refurbing the callipers at some point. Never ending it seems
 
Craig really sorry I have only just picked up your message mate. If you still need any help tomorrow then please call me. Sorry again.
 
At the age that they are and if they haven't already been done then they will almost certainly need it. I posted a good write up for a DIY job if you search "DIY Caliper Refurb" and Oli zcacogp also posted a good write up.
 
Another stupid question - How will I know if plate lift is causing a problem? The new pads went in ok in the end and can move a little now they are in. Would I get uneven pad wear? Brakes actually feel quite good and I did not need to grind the pads to get them in. Just wondering if I need to refurb straight away... Was hoping to spend some time driving the car for a change :)
 
Were the pads that came out worn reasonably evenly? I f so go drive the car! And make a note to check in 6 months time, if not but braking is good - drive the car and work out a convenient time to get them sorted.

If your pads don't slip in and out with hand pressure then the plates have already lifted and are squeezing the pads slightly. This means they won't slide back and forth against the disks freely when you press the pedal. Not a real problem at your current state of lift, but ultimately you will get uneven pad wear and less than optimum braking performance
