Thanks for the tip Bertrand, found your thread about separating the calipers. Now I have an excuse to buy an infrared temp gun

Would you happen to have the specs on the screws?

 

If you don't have a good feel for your ability to get those screws out, I'd leave them and invest the time with a file on the pad backing plates. They are soft steel and file easily. They need to be a snug fit so they don't squeal/vibrate. I use a very small flat file to detail the opening for the pad sensors too. Stamping is often less than precise, plus they get paint in there that makes fitting the sensors tough, future removal/reuse impossible. A little detaiiing with a file there and at the pad ends is a common requirement in my experience.

 

Just installed Sebro front rotors and Pagid pads on a customer 1990 S4 car. He asked specifically for the low price Sebro rotors. So far the brakes feels fine. With the old rotors and pads there were heavy vibrations at hard braking. No vibrations with the new parts.

dr bob: part of me says, leave the screws alone, but another part says, the pads should fit as they come (/filing is for hacks /can't stand that it is not right)). I am sure I will try to get the screws out. If I strip them I will invest in a large metal file.

 

Aryan,
I don't know the screws spec.
You get new screws and the plate in the kit.

Screws look like M6 x 12 or 16.

 

Now I just need a way to protect the piston seals from the heat gun. Aluminum foil maybe.

 

Pistons are ceramic, so no need to worry about direct heat. Caliper is aluminum, and you'll have no luck trying to isolate the heat to just around the screws.

 

I was thinking about avoiding direct heat to the outside piston seals (the dust boots). Anyway I have changed my mind. Driving season is under way and I'd much rather drive than fix stuff currently. Rather than risking mayor caliper surgery I am taking a file to the pads. The rotors measure 30.8 so they will stay on for another season. The in the winter I have the time to do the whole job at a leisurely pace.

 

+2 don't skimp on pads, and other bits..... these cars need all the things that were originally designed with. Leave the anti squeal bits of, and they will squeal.
