Re: Brake assembly

' Hey guys, I was going to replace the pads and now I understand that when replacing the pads then need to be turned to a certain dimension? I haven’t found the drawing yet for the dimension. I was mistakenly under the assumption that you just replaced them. Then I saw the T.O. and the statement "New blocks must be ground, concentric with center hole in brake on suitable machine to a diameter that will give proper clearance for brake in drum as specified on the blueprint of brake assembly."

A "suitable" machine? A lathe? At any rate, it would be much simpler if I could just swap out the assemblies….Do you know of anyone that sells them in the backing plate as an assembly ready to install?Thanks again, Steve in OK. '

A "suitable" machine? A lathe? At any rate, it would be much simpler if I could just swap out the assemblies….Do you know of anyone that sells them in the backing plate as an assembly ready to install?Thanks again, Steve in OK.

'Steve,

A lot of folks complain about the capability of the Hayes expander brakes but I can tell you that I am perfectly happy with mine. The reason .... because I set them up properly from the beginning. I have 275 HP on the front of my F24 and the Hayes brakes hold the plane at high power settings with no problem. When I restored the brakes on my plane there were a lot of issues so I basically refurbished or replaced every part from the masters down to the weels. When it came to installing the brake pads, I wasn't aware of a procedure to fit them so I asked. Unfortunately what I got was, "take a wood rasp and just rake them down till they fit in the drum". I knew there was a 0.010" clearance requirement and that hand fitting was not going to produce an acceptable result in my book. Unaware that there was also a procedure, I took it upon myself to build up the brake assemblies, mount them on a southbend lathe, and machine them very precisely. The brakes must be machined specifically to the drum they are going in. As you know 0.010" is not much room for error. Mic the drum ID and machine the pads OD occordingly. You should be able to get any local machine shop to do this or maybe enlist some help from one of the forum members. Mine ended up dead on 0.010" clearance and they work great. Unfotunately this is not something you can just buy off the shelf as a ready to go assembly. It requires custom fitting for each installation. Also, make sure that the little spring plates between the pads are in good condition. These are what release the brakes. I had a few that had lost their heat treat or spring. I was able to re-heat treat mine and they work fine but test each one before installing.

Hope this helps.

Hey guys, I
was going to replace the pads and now I understand that
when replacing the pads then need to be turned to a certain
dimension? I haven’t found the drawing yet for the
dimension. I was mistakenly under the assumption that you
just replaced them. Then I saw the T.O. and the statement
"New blocks must be ground, concentric with center hole
in brake on suitable machine to a diameter that will give
proper clearance for brake in drum as specified on the
blueprint of brake assembly."

A "suitable" machine? A lathe?
At any rate, it would be much simpler if
I could just swap out the assemblies….Do you know of anyone that sells them in
the backing plate as an assembly ready to
install?Thanks again, Steve in

' Matt, that is some reassuring info. After talking to several of you in the group, I am feeling much more confident. I have everything to rebuild them from the master cyl on down and plan to flush the system with denatured alcohol and probably fill with DOT 5 fluid....have not decided yet. While DOT 5 can't draw moisture thru the air, the one bad thing is any moisture that gets in can pool in a low spot causing corrosion. I really don't think that will be a problem as the PT is a hangared baby and not subjected to any type of moisture contamination like cars and motorcycles, etc. DOT 3/4/5.1 is glycol based and can draw moisture microscopically thru the lines and open master cylinder, but it won't pool. It also should be changed out every 3 to 5 years just to be safe and to prevent corrosion. So much info out there on this subject!!!!
What is most of the group running, Glycol based or Synthetic?
Again, thanks for everyone's help in this!!!!!

  Steve,

A lot of folks complain about the capability of the Hayes expander brakes but I can tell you that I am perfectly happy with mine. The reason .... because I set them up properly from the beginning. I have 275 HP on the front of my F24 and the Hayes brakes hold the plane at high power settings with no problem. When I restored the brakes on my plane there were a lot of issues so I basically refurbished or replaced every part from the masters down to the weels. When it came to installing the brake pads, I wasn't aware of a procedure to fit them so I asked. Unfortunately what I got was, "take a wood rasp and just rake them down till they fit in the drum". I knew there was a 0.010" clearance requirement and that hand fitting was not going to produce an acceptable result in my book. Unaware that there was also a procedure, I took it upon myself to build up the brake assemblies, mount them on a southbend lathe, and machine them very precisely. The brakes must be machined specifically to the drum they are going in. As you know 0.010" is not much room for error. Mic the drum ID and machine the pads OD occordingly. You should be able to get any local machine shop to do this or maybe enlist some help from one of the forum members. Mine ended up dead on 0.010" clearance and they work great. Unfotunately this is not something you can just buy off the shelf as a ready to go assembly. It requires custom fitting for each installation.

'A personal safety item you should know.  When working with the brakes, keep in mind that the pads are asbestos and must be treated with caution when sanding or machining.  Use a proper mask with filters and a good dust collection system to collect the particles.

  A personal safety item you should know.  When working with the brakes, keep in mind that the pads are asbestos and must be treated with caution when sanding or machining.  Use a proper mask with filters and a good dust collection system to collect the particles.

  Matt, that is some reassuring info. After talking to several of you in the group, I am feeling much more confident. I have everything to rebuild them from the master cyl on down and plan to flush the system with denatured alcohol and probably fill with DOT 5 fluid....have not decided yet. While DOT 5 can't draw moisture thru the air, the one bad thing is any moisture that gets in can pool in a low spot causing corrosion. I really don't think that will be a problem as the PT is a hangared baby and not subjected to any type of moisture contamination like cars and motorcycles, etc. DOT 3/4/5.1 is glycol based and can draw moisture microscopically thru the lines and open master cylinder, but it won't pool. It also should be changed out every 3 to 5 years just to be safe and to prevent corrosion. So much info out there on this subject!!!!
What is most of the group running, Glycol based or Synthetic?
Again, thanks for everyone's help in this!!!!!

  Steve,

A lot of folks complain about the capability of the Hayes expander brakes but I can tell you that I am perfectly happy with mine. The reason .... because I set them up properly from the beginning. I have 275 HP on the front of my F24 and the Hayes brakes hold the plane at high power settings with no problem. When I restored the brakes on my plane there were a lot of issues so I basically refurbished or replaced every part from the masters down to the weels. When it came to installing the brake pads, I wasn't aware of a procedure to fit them so I asked. Unfortunately what I got was, "take a wood rasp and just rake them down till they fit in the drum". I knew there was a 0.010" clearance requirement and that hand fitting was not going to produce an acceptable result in my book. Unaware that there was also a procedure, I took it upon myself to build up the brake assemblies, mount them on a southbend lathe, and machine them very precisely. The brakes must be machined specifically to the drum they are going in. As you know 0.010" is not much room for error. Mic the drum ID and machine the pads OD occordingly. You should be able to get any local machine shop to do this or maybe enlist some help from one of the forum members. Mine ended up dead on 0.010" clearance and they work great. Unfotunately this is not something you can just buy off the shelf as a ready to go assembly. It requires custom fitting for each installation. Also, make sure that the little spring plates between the pads are in good condition. These are what release the brakes. I had a few that had lost their heat treat or spring. I was able to re-heat treat mine and they work fine but test each one before installing.

Hope this helps.

' Well dang, closest I have to that is the E&M manual 01-115GA-2 with no inspection criteria. Just talks about "proper clearance for brake in drum as specified on the blue print of brake assembly"....
I would hope that the clearance is the same in the PT as it is in the UC-61 as they are very similar systems....

  Well dang, closest I have to that is the E&M manual 01-115GA-2 with no inspection criteria. Just talks about "proper clearance for brake in drum as specified on the blue print of brake assembly"....
I would hope that the clearance is the same in the PT as it is in the UC-61 as they are very similar systems....

I found this in the AN 01-115CA-2, pg. 96, wheels and Brakes,
25-30 hr.  inspection, 2nd paragraph, " Check
clearance between brake lining and brake
drum.   Clearance should be .010
clearance."Bob

Hey guys, I
was going to replace the pads and now I understand that
when replacing the pads then need to be turned to a certain
dimension? I haven’t found the drawing yet for the
dimension. I was mistakenly under the assumption that you
just replaced them. Then I saw the T.O. and the statement
"New blocks must be ground, concentric with center hole
in brake on suitable machine to a diameter that will give
proper clearance for brake in drum as specified on the
blueprint of brake assembly."

A "suitable" machine? A lathe?
At any rate, it would be much simpler if
I could just swap out the assemblies….Do you know of anyone that sells them in
the backing plate as an assembly ready to
install?Thanks again, Steve in
OK.
