You really would be complaining! http://www.abc.net.au/news/video/2011/01/11/3110493.htm Cliff Myron, Wanna see snow and freeze!! Come on up to Minnesota! It's a daily thing! Sheese!!!

Don't laugh though. My pool "freeze protection" just started the pumps. It is only 7 pm here. My plants look like they were nuked with roundup in the night. No brass monkeys hanging around here. Why the hell am I hanging around here? Oh, and Matco sold me a brake upgrade because the originals were designed for ultra lights at 600 lbs gross as I recall. The upgrade let me easily hold the plane with full power. I ruined two sets of pads in about 30 hours on the first set of brakes. ----- Original Message ----- From: GREGSMI@aol.com To: pulsar-list@matronics.com Sent: Monday, January 10, 2011 8:43 AM Subject: Re: Pulsar-List: Hydraulic Brake Options Okay, original Matcos were much better, not mush, and it is first turn off, not tire off. My fingers must be too far from brain. Got to go shovel snow. Greg In a message dated 1/10/2011 10:37:19 A.M. Central Standard Time, GREGSMI@aol.com writes: Ron, I have flown 800 hours on a 582 with the band brakes and the 5 inch lamb tires. The tires were cheap($12 each) but lasted less than 6 months. When I converted to the Jabiru, I changed the tires to Michelin 5X5. I decided I wanted more stopping power and opted for the Tracy brakes, which were marginally better but still subject to fade if they got hot. I next tried a set of original Matcos that were shipped with the 912 Pulsar. They provided mush better stopping power, but still, not what I wanted. I talked with Matco, at Oshkosh, and they had replaced the orignal wheel calibers with larger ones and recommended I buy those. I did, and they work. I can now do full power run ups and hold the aircraft with the brakes. Now, the down side, I am not sure how much additional heat I am generating when I do those 60 MPH finals, land on the numbers, and make the first tire off. But, I have been able to leave skid marks, so the brakes are working great. Excess heat will melt a fiberglass gear leg, not a good thing, so I try to be very careful with the brakes, but it is nice to know, I can stop quickly, if needed, and not have brake fade. One other thing, I try to hold the nose off when applying the brakes, to avoid undue stress on it. So my recommendation, Matco. They know the Pulsar and are eager to work with you and are very helpful. I would not use any other kind. My next plane will have Matco brakes, in fact, already bought the whole setup, including tires, from Matco. Greg Smith 1400 hours Pulsar\Jabiru 2200 In a message dated 1/10/2011 9:45:25 A.M. Central Standard Time, ronko@att.net wrietes: Pulsar Enthusiasts, I am in the process of converting my band brakes to hydraulics. I got the master cylinder installation well along, but haven't purchased a brake system for the main wheels yet. Here are the options I am very aware of. First the most popular Matco WHLW50CC.75 wheel and internal caliper with WHLAXLE7 axle. The other option I have found which would use my current AZUSA 5" wheels is the Great Plains brake kit http://www.greatplainsas.com/schbrakes.html which I don't know of anybody that has used this system. I also called Tracy Obrien about his C90 brakes which also works with the AZUSA 5" wheels, but he did not have any in stock and seemed reluctant to commit to an order. Outside of the Matco system, is there anybody that has had success with one of these other or another wheel/hydraulic brake system?
