I received the information from Matco. They kept a record of what was supplied to Europa. The brake assembly is WHLB5 and costs $ 98. It is a different shape but is supposed to fit.

Karl.
The brake and parts for the trigear were on my website. I see there was a link problem so I'll fix that this morning.
The only problem with a stuck caliper is corrosion. I pull the caliper and soak the caliper with PB Blaster and then pull back on the brake handle to pop out the puck or use air and recondition them. Why recondition?
The new caliper may not slip right on your original Europa wheel brake mount. That is frustrating.

Bud,
I think I fixed it today. There was some damage to the exposed part of the piston, and the edge of the cylinder. No idea how or. when that happened.I popped the piston using a grease gun with adapter, then repaired and lubricated the o-ring and put it back together. Then spent the next 3 hours trying to bleed that side again, on my own, finally success. With parking brake on I could not turn the jacked up wheel. It seems that even the tiniest amount of air spells total failure.

You are correct.
I’ve popped a few calipers and buffed out the piston and bore then installed new seals and they work OK again. Just remember to clean better than I did the first time. I plugged the bleed hole, tore the seal, etc. Quite the learning curve.
We do it to ourselves though:
Brake lines are run looped over and around stuff where air bubbles can be trapped…Forever it seems.
Master cylinders are set so the reservoir line can’t draw or allow air bubbles out and fluid in. Even the mono.
Some use inappropriate brake fittings and lines.
During installation many don’t realize the caliper should be opened cleaned and the bleed hole checked for clearance of the piston to bleed hole then assemble with the appropriate brake fluid as lube. The new brake calipers often have minor corrosion, swarf and are dry so the initial move of the piston tears up the dry seal lip. These old non anodized brake calipers are prone to corrosion from the inside as well as the outside. That light dust is aluminum oxide and is an excellent abrasive.
During our 5 year nose to tail, we don’t service our brake calipers. Why? It is a pain and a potential disaster.
Some thoughts:
ACP50 should work on the aluminum to help prevent corrosion and not destroy the seal.
During a 5 year maybe I will pull the caliper…Carefully extend the piston, clean, inspect, coat and push back in.
We should change our brake fluid as Dot 3-4 are glycol based and absorb water.
Dot 5 silicone allows water to pool in the bottom of the caliper. Turns color if water exposed to a dark red.
Mil 5606 gets sticky and can freeze a piston when exposed to air.
Replacement brake calipers may not fit your current torque plate brake/caliper slide support.
Some second hand owners/non builders use the wrong fluid with the type seals they have, and don’t realize it because of ignorance or the builder didn’t document it and put it in a format the new owner had access to.
I’m finally getting around to document my aircraft more completely after 12 years. I plan to put it into the POH. Similar to the spares page on my website but no pictures. It will have not just the fluids, but the common annual items also with torques just for a memory jogger.
Today we have no excuse not to have all our data on our cell phones. I have all my manuals, parts lists/numbers, wiring diagrams, etc. on the cloud. Now that I have so much more storage on my phone, it will go on my SD card. I even have my cross country flight planning checklists, notes, and medical stuff all handy on my cell. I don’t have my build manual pdfs on the phone, but if I need that, I’m going to be on the ground long enough to get on the web. Again, with my phone.
Best Regards,
Bud Yerly
