My front passenger caliper has a frozen piston.

Dunno how they worked so well unless I baked at at the last DE I did with it.


Does anyone have a known good front passenger caliper to match the other on my 72?

Rebuild time!!

ALL of the calipers were this way on the 74LE. Scariest thing I have done is to get those pistons out of the caliper. Sounded like a shotgun blast for each one. You have to use an air compressor attached to the bleed port. Cushion the caliper area, mine looked like a big rag cause I had a towel wrapped around it and BOOM out they come. It gets real scary as the pressure got up to 200PSI before they let loose. Be careful when doing this. These are not bad to rebuild, get a kit for each one - and I would do both sides.

.. keep hands and all valuable objects out of the caliper.

100...120...130........180psi BOOOM.

very entertaining

What would you use if your compressor only goes to 150?

I've got a pair off my 74 they were fine when I took em' off and carefully stored....sell em' for cheep. How'sa bout 20 bucks + shipping?...or trade for a 914 hat?

Wouldn't it just be easier to take the caliper off the rotor and put a piece of wood in there and use the hydraulic pressure of the brake system to break it free? I'm sure that the pressure in a brake system is more than 180psi. And liquid doesn't compress.

it may work at 150...

I actually did mine with a cheapo tire inflator that plugs into the cigarette lighter outlet. Something like $20 at Walmart. Has a gauge and goes to 250PSI. Used a piece of old plastice fuel line jammed into the end of the tire inflator and it fits over the bleed nipple. You may have to help hold it on the bleed nipple. BE CAREFUL - this can go BOOOM.

I have some calipers available but I'm not sure of their condition - came from parts cars.

The signal orange 72 has working calipers but they won't be available until after the FFC.

I'd go for the "use the hydraulic pressure of the brakes methood". It is easy to do, more controlled and far less dangerous.
Just be sure to do it slowly and keep your master cylinder topped up as to not get any air in the system from that end.

Well as exciting as an air compressor is. I used an old bicycle hand floor pump. only took maybe 50PSI and had a block of wood inbetween pistons. The 1st one to start moving gets a C clamp till the other side gives way.

Air compressor is cool till someone looses an eye. or finger.

JP,
didja get my PM?
