Looking for your thoughts on this issue.

I’ve had my car serviced by a main dealer, on collection they told me that one of the bleed nipples on a front brake calliper had snapped off. The car is drivable as there is no leaks, it must of snapped off while being tightened after the brake fluid change, which seems a bit odd to me.
The dealer expects me to pay them £800 to repair the calliper. I have argued with them as I think they should cover the cost, as it was them that snapped it, they don’t accept that, as they say sometimes the brake nipples do snap off. The dealer has offered to cover the cost of removing & reinstalling the calliper with me picking up most of the cost to get the snapped bleed nipple machined out.

Interested to know you guys thoughts, do you think the dealer should pick up the whole cost, on the basis it’s their liability or should I accept they’re offer to cover the cost of removing & re installing the calliper with me covering most of the cost of having the calliper repaired?


Thanks. Steve

it's not uncommon for bleed nipples to shear, generally when trying to open them due to been overtightened previously and then seizing slightly over time. When it comes to the next maintenance they fail and the garage doing the work gets the brunt of it.

There's plenty of independents who should be able to sort this for a lot less than quoted

I had a similar issue with a main dealer snapping my handbrake cable and then telling me to pay for it. Ended up paying for parts only but did not enjoy the experience of being told the cable snapping was my fault for never using it (despite using it every time I parked the car). Wonder if it is the same dealer?

I had the same happen to me on my previous Vantage and a Range Rover Sport . On the RRS it was 15 yrs old and having bi-yearly services due to low miles, so I blamed that, ended up with used refurbished caliper being fitted.

On the Vantage I had been stretching out the service intervals during Covid, had barely done 2k miles and it was probably 20 months since previous service....which was a good excuse for the dealer to blame that as obviously they undo/redo the bleed nipples yearly (dont they?)

The dealer quoted £300 for a special engineer visit to get it out but the engineer didn't succeed. I ended up paying for a new caliper, they gave me some discount on it and fitted as part of the service, but it still didn't leave a good impression, after all the car didn't go in there needing a new caliper. Made me cautious. Since then on my cars I've been slightly moving the bleed nipples myself after 6 months or so to make sure I dont get any excuses come service time.

I think they probably snapped it while attempting to loosen it, the bleed nipples are terrible to undo, too much force and then you'll snap it, if they don't move you need decent penetrating fluid like plus gas or Rost off Ice.

You need to remove them all, one at a time, and put a tiny amount of silicon grease just on the threads and retighten, plus make sure all 8 are moved every year when the garage performs a brake bleed then you'll be ok.

My brake nipples were awful years ago until I did the above, plus never snapped any of mine.

It's a simple caliper with no mystery. There are many independent garages that break them every day in all sorts of cars .
I would not expect more than £100 to get it out , just find a garage and have a replacement ready when you book it in.

Unless you already have I'd be inclined to ask them if they actually bled that particular limb of the braking system (i.e. did the nipple break off trying to open it, or when they nipped it up - I'd guess the former)
If they said they managed to open the nipple and bleed the brake but it broke on re-tightening then it's a candidate for an "easy-out", as it's recently been moved and it has a hole down the middle ready.

If it broke off trying to open it then it could be a (very careful) drill out job.

Thank you all, for your feedback & suggestions. I’ve had ago at removing it myself, with stud removal tools, I got loads of torque on it, even with an extension bar it would not budge. I don’t want to try anymore as I may right off the calliper. I will take the calliper off & will see if it can be machined out.

Does anybody know of a machine shop in the Bristol area that could have ago at machining it out?

Thanks

Seems to me a better design of brake nipple is needed. Something that breaks every time you try to use it and costs £800 to fix is a bit silly IMHO.

Mine is off for a service tomorrow; let's hope they don't break them.

Not insulting you but did you use heat ?

Yes i did use heat & also tried with it cold. Also pulsed the torque i was putting on it, it would not budge.

When mine snapped I removed the caliper and took it to a local welder who managed to weld a nut onto what was left of the nipple, the nipple then came straight out. The heat from the welding possibly helped.
I now as a matter of routine crack off all the bleed nipples every 12 months so they dont sieze

Once sorted that's what you need to do.

Got any crayons?

Heat it up and melt a wax crayon into it, the capillary action pulls the wax down the thread and you'll get it out.

Brembo? So common, it's not overtightening it's galvanic corrosion, ally caliper, steel nipple = hassle. Usually only chance is spark erosion to get them out.

|Someone I know sheared them on a Volvo Polestar, that was an issue as the calipers were not only incredibly expensive they were unavailable.. car was sat for a long time until they found someone who could erode them out without trashing the caliper.

It's also worth removing the calipers and putting anti seize on the bolt shafts where they go through the caliper (NOT the treads!)

The people who serviced the car are 100% responsible and they know it. They just want don’t want to pay for thier mistake. I am in the USA so I don’t know how insurance works in England but I would turn it into my insurance company and see if they will cover the claim. If they do the insurance company may go after the repair shop.

Completely disagree with this. It was YOUR corroded bleed nipple that broke off, certainly whilst trying to remove it. A very common problem and the only time this would be warranty is if the car was still under manufacturers warranty. A garage is simply not responsible for broken and sheared rusty bolts. The only caveat to this is if we had a car in and it was almost certain we had to use excessive force to remove a bolt, we would call the customer and ask them if they wanted to proceed at their risk in an attempt to remove it.

If a garage was to be held responsible for manufacturing faults or corrosion, they would never touch older cars.
