good luck,

PS... I have these bushings on my e39 M5 from a year or two ago and they fit VERY tight, broke one cheap c clamp installing.

I could finally get an answer from ECS and they are replacing the kit. I've tried the bushings I have here on another set of calipers and they also fit loose. Hoping the replacement set will fit well.

When you get your replacement bushings, what you should find is that when you go to install them you should only be able to insert them about a 1/4", maybe just a bit more by hand. From that point on you need the installation kit that you already have and a big C-Clamp ( I think I used a 10 or12") and it should be tight.

I've decided that I'll no longer buy anything from ECS, therefore I am not going to have replacement parts, I am just returning the bushing kit I have.

Thank you for your input though; much appreciated.

Buy them, can`t go wrong with this

I see on Bimmerworld's website that when BW's rear brake caliper bushing guides are installed on an E9X M3, that the rear's caliper retaining spring is not needed anymore. Is the front brake's retaining spring not required after installing Bimmerworld's front brake caliper bushing guides?

I don’t recall not reinstalling any springs. What are these springs?

were you able to delete BOTH the front and rear brake catch springs when you installed Bimmerworld's brass bushing kits? Or did you put the catch springs back on?

I bought the Bimmerworld brass caliper bushing kit for the front and rear. I'm having some clearance issues where I cant fully seat the snap ring on the front caliper guides. Its due to the shape of the snap ring where its thicker and hitting the caliper itself. Mind you I'm installing it based on the notes where the snap ring faces the inside of the caliper (next to the piston). Tried to do it the opposite way but the area is more confined.

I've tried using c-clamps to fully push the guides in and tried to mill off some caliper material for better snap ring clearance but still having issues. The instructions call for using the 18mm snap ring on the longer (bottom) caliper guide and the 19mm snap ring on the shorter (top) caliper guide. Can't get snap rings on either the longer or short caliper guides.

The rear bushing were much easier to install given the additional length. Has anyone encountered such issues for the front? I'm thinking either every caliper is slightly different or the production for this batch of caliper guide bushings are slightly too short.

Interested in results. Been looking at both the bimmerworld and ECS kits. Was leaning towards ECS due to the included cap for best dust protection.

[slowdown_dan]

Cap will degrade if you take it to the track.

So funny story, I did purchase and install the ECS front/rear kit. Also used their install tool and everything went according to the PDF instructions. However, of the 8 caliper bushings, only 7 needed to be pressed. One of the "long" bushings slid right in and is free to rotate/slide back and forth.

Does anyone with the ECS kit have any experience with this?

I emailed ECS asking if this is "acceptable" or not. We'll see what happens. I won't drive the car until I get an answer back.

[patroklai]

Ran across an Audi thread that is a few years old. Directly from ECS/Jason:

"Depending on how much rust you remove from the caliper you can definitely have issues with the tolerance of the bushing. Using a bearing/sleave retainer to help hold the bushing in place of caliper bores that are slightly out of spec is an acceptable method."

He's specifically referring to: "Permatex 64000 High Temperature Carded Sleeve Retainer. It's for press fit bearings or sleeves that are slightly out of tolerance."

Got my hands on it for $8 from a local auto store. Will reinstall the one sleeve tomorrow.

[patroklai]

Did it. Worked like a charm.

I tried to do this again while installing my brake shields and used the other caliper guide. This time I toke some pictures to show the issue. I was thinking if I put everything back to together with the unseated snap ring, it could maybe seat when fully depressing the brakes. Thoughts?

Pictures show some gouges in the caliper paint where I tried to remove some material before.

[patroklai]

I thought that snap ring was supposed to go on the other side. I don't have this kit, but rather the ECS one and there's nothing securing the bushing on the inner part of the caliper. Only the outer part.

[ppatel14]

Bimmerworld instructions say to install the snap ring on the inside next to the piston.

[patroklai]

What does bushing look like? Is the brass bushing groove closer to the side opposite to the bushing lip? If so then you've inserted the bushing from the wrong end. Per those instructions, those bushings are inserted from the outside of the caliper and the lip/seat of the bushing should be visible externally, not on the piston side (inner face).

So I would assume once inserted this way, you'll see a groove on the inside that allows the snap ring to secure on to the bushing.

It's interesting how these are installed in the complete reverse order when compared to the ECS

Exactly, lip is supposed to be on the outside. I tried it both ways but due to the shape of the snap ring, it doesnt fit. Oh well, I'm in the market for a BBK or some type of retrofit so calipers will be changed out. Thanks for your help.

[patroklai]

Have you tried installing them the ECS way? Same placement you have going on but with the snap ring on the other side.

Does the Bimmerworld instructions mention you don't need to run the spring clip after installing these brass bushings? The YouTube video that was linked, the person said no. I downloaded the ECS instructions for their version and it didn't mention removing or installing them back.

What about you guys who are running these?

Yeah I just ground down the caliper a bit. The casting was not flat/level enough so the clip was never going to seat properly.

just put them back on? they will minimize any pad movement still left after the solid bushings. Takes 2 seconds to pop them back on.

I removed them from the rear. I didn't see the point of them.

I still havent installed the front caliper guides nor gotten a BBK.
