Glue and brake linings

[avenger1949]

What is the preferred glue for attaching brake linings. T88 isn't really a high temp glue and the one suggested by a paper I got isn't available in the US?

Re: Glue and brake linings

I've used Pliobond #20 for the last couple sets of linings I replaced. It worked good and is easy to remove when you go to replace the linings. I used TorqueLock on the first set but that stuff is way to aggressive and is hard to remove. You could make a set of wheels out of that stuff. Other good options would be Marine-Tex or PC11. These are waterproof and can take the temp....whatever is lying around the shop at the time. Good luck....

Re: Glue and brake linings

Thanks that helps a lot... I would rivet them but my skills there are reallllly bad.

Re: Glue and brake linings

get the correct rivets and the tool to install them so you are legal

Most owners do not care about legal, only what is easy or cheap!

Re: Glue and brake linings

I don't think anybody is going to jail for epoxying the linings in the wheels. I do it so I get twice the life out of a set of linings (countersinking the rivets eats up about 50% of the lining thickness). I guess if you are landing on long runways and only use the brakes to manuver on the ground that would be fine. I use mine to actually stop the plane on short sand bars and as such, wear out a set of linings per season (if I'm lucky). I'm getting the sleeves for the tapered axles made right now so I can get Cleveland or Groove brakes installed. Hopefully my days of 'illegally' epoxying linings in those stupid Shinns will be over very soon.

Re: Glue and brake linings

My strip is only 1300 ft long so under perfect landing conditions I don't use the brakes so that said I probably use them 30% of the time to stop the plane. As for legal, it is pretty hard to find a real legal plane and pilot anymore. Don't really care about cheap when it comes to flying but know I probably don't have the skills to rivet it and would feel safer with glue then my rivet job. I do appreciate the advice here and would like to thank all for their feelilngs on this subject.

Hi,

Just my two cents. No IA should approve this. It is his license on the line to do so. If you would have some type of landing accident you know how the Feds would make this an issue, even if it didn't have anything to do with it. Your insurance, if you carry any, could decide not to pay out.

I epoxied a set on my first BC-12D I had and it worked very well. I did not use any exotic epoxies, just a thirty minute, two part, hobby epoxy. To remove, use a heat gun and then clean up the residue. Riveting is a pain, but that is the way it should be done. There are several posts on this forum from our friend's overseas who have used this method to attach linings. There are also several posts on here that instruct how to rivet linings.

Re: Glue and brake linings

This is how I got rid of the worthless shinn brakes go to technical section and look in wheels and landing gear under Grove brake 337 this is the best thing i have done to my plain Chuck

Re: Glue and brake linings

Marty's comments on insurance are very true.

The companies may well look for a reason to deny coverage.

An unauthorized type of repair provides just that.

Every insurance app I've ever seen asks ; " Valid Airworthiness Cert?".

"Yes" means you agree to operate per FAR 91, 43 , 39 etc.

Whether the insurance company can deny coverage for non-related

incidents varies by state law.

Re: Glue and brake linings

The rivet tool below works well. Check the link:

Brake Lining Rivet Tool

Aircraft Spruce has them, as well as others. (Wag list them as no longer available on their site) I modified it a little by grinding off as much from the corners as I could on my bench grinder. That let me put the new rivets on without having to remove the tires. Just deflate them a little and it gets right in there. It's really pretty simple.

Re: Glue and brake linings

The $5 extra for Deluxe can be well spent.

My choice is not to use a hammer ( All Purpose Tool?) while doing this.

The threaded screw on the Deluxe allows better control.

When using the Standard model I like to squeeze the tool in a vise.

Re: Glue and brake linings

If you are going to stay legal in the U.S. you have to use rivets (unless you want to do the paperwork to get authorization for an alternate compliance method, if you DO please share it). That said, with the current state of the FAAs budget they are most likely not going to tear down your wheels and tires to check. That DOES NOT MAKE IT LEGAL. There are lots of things that we can (and probably should!) do to our planes to make them safer. Some of us do it. But you really don't want to draw attention to unauthorized mods if you ever have an accident. The insurance company is another subject. They are fully justified in denying payment if you aren't in conformance.
I am pretty ham fisted with rivets and I riveted mine (with an A&P watching me). It was NOT that hard. I think I only screwed up one rivet and it was drilled out and redone with no problem. It is a LOT easier with a rivet squeezer.

Re: Glue and brake linings

Some insurance companies hire A & P's to check for non-compliance.

Re: Glue and brake linings

That's interesting. Non-compliance to what? May I ask upon what basis this applies to aircraft like the Taylorcraft where detailed design data is 70 years old and hard to get hold of?

May I also ask which A&P that you know would have access to the detailed design drawings of the Shinn brake lining assembly, as applicable to the Taylorcraft, to definitively argue in court what is legal?

My questions are genuine, because I think that some of you US folks are too over-enthusiastic about legalities to the point of them overcoming common sense.
