Brembo Caliper Bleeder

[loots06]

A few weeks ago I picked up a set of Brembo brakes with SS lines and Baer rotors front and rear. The rears came with caliper relocation brackets. The caliper were milled 5mm at the mounting points in order to run the Baer rotors. They also came with 5mm washers in the event I wanted to run the stock GT500 rotors. It’s a pretty sweet set-up.

I wanted to be different so I sanded and painted them red. I got them install pretty simple process. The brakes worked great and you could definitely feel the difference. Anyhow, a couple of days ago I noticed a leak and brake fluid on the inside of the wheel. I removed a wheel and tightened up the bleeder and though the problem was solved.

Yesterday I noticed a more brake fluid on the inside of the wheel. I removed the wheel for a closer look and saw what I believed were threads sticking out at the bleeder. I’m glad the brakes did not fail because when I was driving because things could have been much worse.

I’m wondering if it’s possible to tap and thread the Brembo brake caliper or am I at total loss. Any advice or help would be greatly appreciated. I’ll post pic’s in a few. In the mean time, I’ll be rocking one Brembo caliper and one stock. I don't drive the car to much so it should be good.

I don't see why you couldn't tap it one size bigger if you can find a bleeder to match.

What about a heli coil? Here are some pics.





I hope it could be saved. I'm gonna contact brembo and see if I could purchase the back half of the caliper.

Ewww that sucks.

I'm doing some research and it looks like I'm not the only one with this problem.

I don't think a heli coil would be a good idea on a brake caliper bleeder. There are plenty of variety pack bleeder screws at parts stores. Just grab one and tap it to the next biggest.

The problem with the next bleeder size (7/16) is the amount of metal remaining. I'm also looking at a Dorman bleeder repair kit or a time sert. I'm only way to the shop to drop off the time sert. If I'm right the time set measure 11-11.5 which should go right in the existing hole. All I'll have to do us thread the hole using an 11mm which should be a tight fit. Even tighter with thread sealer. I'm going to check if I could use the same bleeder.

Fixed...

Hey so here is my problem, you "thought" you saw threads, can you confirm before you do anything?

do you perhaps just need a new copper washer?

 

[loots06]

The threads came out with the bleeder! Pic confirms stripped threads, copper washer won't stop the leak at the nipple of the bleeder.

What I was saying is to drill it and then tap new threads. Heli coils and inserts will require this to be done as well. I feel like a heli coil adds more possibility for it to leak again though.

I had this happen and there isnt enough material on the bleeder to drill it out to the next size. ever repair kit i found said something like 1/4" material after moving to the next repair. On brembo stock is close the 1/8" material. I purchase new calipers to be safe. Almost the same thing happened to me it just started leaking one day and found the threads where stripped. Luckily it happed when the car was parked in the garage. car drove find one day and the next the brakes wehn to the floor after starting it and trying to pull out of the garage

I hear what your saying. After some research I found that a M10x1 (.08 overall length) time-sert will work. The overall diameter of the time-sert with threads is 11.18mm and requires a drill hole size of 10mm, which is where is it at its current state. In order for this to work properly I need an 11mm tapered tap. I've ordered two different types of taps one tapered and the other plug style. When it arrives all I should have to do is just tap new threads screw in the insert and call it day. This should not leak because I would be using the original bleeder.

Just be sure to use a good bit of thread locker to lock and seal the insert well.

Believe me ill do plenty of testing in my driveway.

So I was able to install a time-sert into the stripped bleeder hole in my Brembo brake caliper. I picked up the two different time-serts, M10x1 with a .08 length and M10x1 with a .062 length. As I previously mentioned the overall diameter of these time-serts were M11.17 and requires a 10mm hole.

The most challenging part was finding a M11x1 tap. Fortunately I was able to find one on Ebay and the other at Metric-tools online. When I tap arrived all I had to do was tap the new treads. Keep in mind that I didn't purchase the complete tap set because I didn't want to spend the $200 bucks on a tool set that I might one use once.

Anyhow, filled the bleeder hole with grease to prevent and debris from falling into the bleeder. I tapped the new treads and used the .062 length time-sert because the other was too long. I used compressed air to blow out the grease/debris from the brake line connection. I used a tread sealer on the insert because I wanted to ensure no leaks. Just so you know the new treads with the time-sert made for very tight fit. I then carefully tapped the edges of the time-sert. I let the caliper set overnight to allow the tread sealer to cure. The following day I bolted up the caliper bled the brakes and checked for any leaks. I'm happy to report that I have not had any leak from the repaired bleeder. So far I must have pumped the brakes more the 50 times. I plan on checking the caliper again before I hit the road. Here are a new pics.
