    Great repair Adam. I worked 35 years as a tool and die maker building aluminum welding fixtures, every threaded hole was called out from engineering to have a stainless Heli-Coil® insert. Holding strength is quite a bit stronger than just aluminum. The insert tool actually shrinks the insert a bit while threading it in, as long as the top and bottom of the insert is engaged in the aluminum they will not move. The ends of the coil will actually bit into the aluminum. Thread locker was not recommended.

      @KJ6EAD ปีที่แล้ว +1

      How can you get the ends of the coil to bite, especially the top. I understand the pressure from the bolt being tightened would do this to some extent but wouldn't it help a lot to peen the aluminum at the ends of the coil?

      @@KJ6EAD when you break off the tab at the bottom it’s designed to have a small burr pointed out into the aluminum and at the top it’s sprung out just a bit to not allow it to back out. At least that’s how they were designed when I was using them. I’ve been retired a couple of years so not sure if they changed anything.

    I’m a Subaru Tech of 20 years. This is a spot on repair. Fairly common problem and helicoil is more than sufficient. I’ve never had a helicoil brembo fail. No need to split calipers. That just damages the paint around the bolts. The owner can clean where necessary. 100% great repair exactly how we would do it.

    With these Brembo calipers on the rear of a Subaru. This is a common issue. But to save time. You can unbolt the calipers and they will halve. Then you will have a machined surface to work off of. The rebuild kits for these are about $30.00 so you might as well do that while you are at it. I just would not use the lube to put the coils in. They might back out with the bolt on the next service. I use blue lock tight on the inserts. I have done a few pairs of these in my 32 years as a mechanic.

    I appreciate what a few of the others are saying that it would have been better to split the caliper (allowing inspection the pistons and bores), but the video is primarily an Adaptix first use, rather than a Brembo repair, and without the novel workholding could be one of several in the Abom backcatalog.

    I don't use helicoils on brake calipers, Wurth Timeserts are a much better option for something like these, there's no skimping when it comes to brakes. A much easier way to hold the caliper is to split it, and bolt the mounting half to a steel plate using the four bolts that hold the two halves together, then mount the plate into the vise.
    If the caliper is a monobloc type then use a small mastercylinder connected to the banjo bolt, to pump the pistons out and clamp a steel plate using a couple of shims to save damaging the pistons, and lock off the lever of the mastercylinder, and then mount into a vise clamping on the plate.
    Both methods work cleanly and effectively.

    • @clivewilliams3661
      @clivewilliams3661 ปีที่แล้ว +2

      In actual tests Helicoils outperformed all other thread inserts, including Timeserts. The tests were on maximum torque application and direct pull out. Essentially, a Timesert is a tube that is both threaded internally and externally although it does nave a tapered section at the base to expand out to supposed lock into the threaded hole in the parent metal. The Timesert can only have full contact at the base of the insert, where it is tapered all the rest of the threads relying on a loose fit. The Helicoil is a tight spring with sharp coil sections that form the thread. When a bolt is tightened in, the ramping action of the bolt threads against the coils of the insert pushes them out into the parent metal giving full depth pressure to the sides of the hole and digging the spring section in. The Helicoil material is high strength alloy steel so that the parent material will always be the one to fail, when it eventually does. Given the relative price of Timeserts against Helicoils, using Helicoils is a no brainer when they outperform them all
      Timeserts have their place. In a VW air-cooled crankcase the cylinder holding down bolts are close to the holes for the cylinder barrels and the bolts have a bad reputation for stripping the crankcase thread especially in high performance application. The use of Timeserts is normally prescribed and I would recommend them over Helicoils because there will be radial pressure that could break the bolts and helicoils into the cylinder barrel holes. Using a Timesert reduces this radial pressure and distributes what there is around the outside of the timesert and into the body of the crankcase.
      As I said previously, Porsche use Helicoils to mount the brake calipers to the alloy swing arm. Porsche are renowned for placing engineering above all else in their cars so would have deliberately selected Helicoils over all other options

As for a caliper mounting bolt which is likely to be on and off as the pads are changed in use, I find Timersert better for these applications, and less likely to wind out on the bolt in time.

      @@mickymondo7463 What type of failures have you seen with Helicoils, the actual Helicoil or the failure of the surrounding metal? I suppose that with a Timesert you can loctite it in, that is not advised with a Helicoil. Really, the only time you would need to remove the caliper on a car is when changing the disc or the bearings that could be less frequent than changing pads, which can be done with the caliper in situ. I must admit that most times i change both the caliper and disc at the same time as with the non-asbestos pads they have to use a softer disc material that typically wears at the same rate as the pad. However, on our family car I only had to dismantle the front brakes once at 130,000mls to replace the pads and discs although even then they weren't at the wear limit. My performance/competition cars generally require pad/disc replacement at about 50,000mls so even then its pretty infrequent. I've never changed the pads or rotors on my Aprilia RST although that only does around 3,000-4,000mls/ year

    Yesterday, it so happened my shop had a job, also as featured an aluminum brake caliper. From the casting as surface towards wheel rim, the slight variant exposure saw interference at wheel install. The customer as changing from a larger, aluminum rim with larger tire size to a summer tread. The repair was simply very careful, dimensional grinding to allow free travel. And where, the cast region was very rough, with large variant rear surface as caliper. As left to right, both featured a very similar dimension as material removal. The job completion saw high temp paint to protect surfaces. For the tech at install, inspection of the piston as face and where rubberized boot, is a key feature to delivery as long life.
    The install of the hili-coil was a great lesson. Several of the tips I had not found but clearly are useful to gain the strength and centering to repair. Thank you, for having me along. M.

    Excellent demonstration of the usefulness of the Adativ Vise...As an extra precaution, a piece of painter's tape over the brake banjo bolt hole would eliminate the slight possibility of tiny chips from entering the fluid cavity ...

    Use loctite on those helicoils so they don’t back out with the bolt
    Those bolts require loctite when installed so it’ll stick to the thread repaired and sometimes pull them out when unscrewed
    I usually put some on the helicoil and also pin both sides of the thread when installed so it mechanically lock it in place

      Yeah I was thinking the same thing. One tight thread and those helicoils are backing out of the caliper. Vibration and thermal expansion are probably gonna see those calipers loosen.
      Even my cheapie helicoils knock-offs have a mechanical locking mechanism to prevent them backing out. Glad I didn't buy helicoils are seeing them used.

    I've installed many of these in aluminum parts. Possibly the worst are VW engine mounts which use torque to yield bolts into aluminum. This causes shear in the threads of an Al casting, failing with new bolts. This drops the engine as the threads pull out.

  • @timhochstetler4515

    why didn't you loctite the threads in position?

    • @clivewilliams3661
      @clivewilliams3661 ปีที่แล้ว +3

      Normally helicoils shouldn't have loctite on the threads because the way they work is that as the bolt is torqued the ramping action of the bolt threads on the helicoil threads causes them to expand out into the parent metal. if you use loctite you risk breaking the loctite seal when the bolt is torqued up and the loctite can squeeze out to contaminate the bolt threads, causing the bolt to be thread locked to the helicoil and the helicoil not being fixed to the parent metal - remember the helicoil is effectively a spring. However, having had the situation where after a time the bolt corrodes to the helicoil and the helicoil begins to wind out when the bolt is undone. This causes a problem because the helicoil generally can't wind back through the caliper mounting hole and the helicoil gouges the mounting face. This happened to me with a Brembo caliper and Porsche swing arm. I didn't follow conventional wisdom and peened over the aluminium to stop the thread winding out again and made sure that the bolt threads had anti-seize lubricant on.

  • @budlvr

    18:50 ? I would have thought a HeliCoil would go in with LockTite and not a lubricant? The 'internet' says its up to you, but don't get it on the inside of the coil. Great use of the new jaw!

      I wondered about that too, but if this is aluminum it galls really easily.

    • @AndrewMerts
      @AndrewMerts ปีที่แล้ว +3

      Part of that is because when installing it you're twisting it in from the bottom tang which causes it to narrow down and twist tighter together when there's more drag on the top threads. Once that tang is gone the insert is going to be working like a spring slightly pressing into the outer threads and when there's a bolt or something being tightened into it any friction is now going to be at the top instead of the bottom so it'll work to unwind that spring and force it into the outer threads even more. Personally I still use loctite but the helicoil probably isn't going to move after installation without it.

      The coil is more of a interference fit then the bolt for one and the clamping force when tightened the bolt also holds the coil to the new threads, these may look janky but have been proven for years, very good fix solution in many cases

      @@skippybuilt I watched the video a few more times after I commented - yeah, you can see the coil is reasonably tight against the thread, and when the bolt goes in it seems to go in freely, almost a little loose. So I guess when it’s being tightened down, it doesn’t exert any force on the coil until right at the very end. Good explanation though, thanks 🙏

    • @Peter-V_00
      @Peter-V_00 ปีที่แล้ว +1

      That is why you need the insert tool to put the coil in, it tightens the spring so it will screw in, then when the tool is withdrawn the insert expands against the thread locking it in the bore.

      @@ZylonFPV This is the case with a plain threaded bolt, too. There is no clamping force on the threads until the end of the cap hits the surface of the mating material. This is why torque processes in manufacturing can sometimes require quite a bit of study to get just right.

      @charlesnoneofyourbuis5819 ปีที่แล้ว +1

      WITH 1 exception. NEVER countersink a brake caliper. They are machined flat from the factory for a reason. Any movement of the new bolt will put torque on the helicoil and give movement to it when torque is applied to the bolt. It will deform the helicoil. I KNOW for a fact it loosens up the helicoil and you never want the bolt to stress the caliper. Been working on cars my entire life. Never countersink a brake part. It is meant to hold in place with two flat surfaces.
