I recently stripped the caliper mounting bracket on my brembos, and i bought a new set of a trader on here, now my question is is it worth helicoiling the old ones and selling them on? would a helicoil be reliable enough to hold the caliper. any thoughts?

 

Worked perfectly on mine when the bolt sheared

 

It also worked fine on mine (non Brembo but same part).

 

I'm sure Godspeed offer this as a service, so it must be ok.

 

I wouldn't trust a helicoil on brakes.i had a timesert or steel insert fitted when I stripped my brembos.

 

We have helicoiled hundreds of calipers with threads damaged or pulled out , and if done correctly will be stronger than it was standard , we have never had an issue in doing them
Cheers Ian

 

Thats great thanks will go ahead with it so cheers.

 

My rears have been helicoiled by Ian.

But what boils my p*ss is that supposed marvellous German Engineering Brembos don't have inserts cast in to STOP the threads taking up.

 

Mine have been helicoiled

 

ive seen helicoils back out, i used time sert when i did the nipples on my ap`s.

 

I thought helicoils and timeserts were identical!?

 

nope, timesert is solid wall. helicoil is just singular wound strand.

timesert is more expensive, i had to import from states, but dont have to worry about catching and you can saw timserts to length.

 

hellicoiled a fair few sets of brembos without any adverse effects

 

Have hellicoiled loads of calipers on rally cars with no issues and if they can deal with that kind of punishment then there more than capable on a road car.

 

Helicoiled my old ones to coarser thread than Subaru standard. I think I did them to M12 x 1.75 rather than M12 x 1.5. I think the Evo Brembos are M12 x 1.75 as standard and they don't strip threads as often as the Subaru ones do. Also you can pick up new bolts at any fastening company.

 

Seems to be quite common for the brembos to strip.

 

Yes.....it's to do with bimetallic corrosion.

The bolt is steel, the caliper is alloy, when damp, together they make a tiny electrical cell, which effectively eats away at the steel, and it swells.

Then, when you try and remove it, it "takes up" the threads in the alloy.

But of course, Brembo, being a quality product, know this might happen, so they design their calipers with inserts........oh.....wait....

 

I did it to my AP's years ago and haven't had any problem since.

 

I am a machinist to trade and often helicoil brand new aluminium components as par for the course, this gives a stronger and harder wearing thread than just plain aluminium.
