I have cleaned the front brake calipers, changed the brake discs and pads, and used copper grease for lubrication.

I now have an imbalance of 30%.

The near side shows 108 KGF and the off side shows 75KGF.

Does anyone have any ideas.

Thanks

 

hi scruffy

could be that the new brake pads need time to bed in as often happens when you do this kind of work try it again after you have done a few hundred miles

Can it be air?

p.s. Which side did you do first?

 

Update:-

Found out that one of the caliper bolts has stripped its thread in the carrier and therfore the caliper is loose as only one bolt holding it in place.

Rather than change the carrier at great expense I thought I would use a Helicoil insert.

Does anyone think this is a bad idea?

 

Scruff... although helicoils work pretty good, I don't think I would use one on such a high safety item.

I second that. I would spend the money to fix that properly

 

@Scruffy: You are talking about the two long pins, each about 6mm in diameter, holding the brake pads in place. Correct? In that case it's not a problem, because they do not carry much load – and as a reminder: "Heli-Coil is the approved Screw-Lock Screw Thread Insert source for Boeing Aircraft per specification BACI12AE Rev B." I would say no problem

Thank you.

It is as I thought.

Will sought it out on Monday and let you know next week if it cures the problem.

 

Master Chief.. have you read this spec? I review specs on a daily basis as a Mechanical Engineer and they can be very specific. Just because it is used in a airplane or the Space Shuttle, does not make it an inferior product. Maybe it is used on certain parts of the aircraft and not others. I have a friend that works at Boeing. I will ask him to see if he can get me any specifics of the spec. I just want you to be sure about what you are recommending. When it comes to brakes and lives are involved, I would be careful.

As an engineer and having used helicoils for years, I would fix it by replacing the components.

Yes, replacing a damaged brake caliper might the best option, and is recommended by Chrysler. And yes, using a Heli-Coil might even be verboten in/his your country, and make you/him liable. However, that's up to the person in charge of the work being done.

And anyone getting information from the Internet is advised to verify the given information. Especially when it comes to the safety of your family. I am however pretty sure that Scruffy will verify the provided link/information.

Now back to the daily routine with a Heli-Coil in my left front brake caliper (lowest pin) for over two years and 40.000km!
