You cannot be serious Neil? Carbon brushes with copper tails are spot welded to their fixings within each holder. Holders wear as badly as the brushes within them anyway. Coupled with the fact that carbons brush kits are cheap and readily available anywhere so what is there for you to gain by messing around with them I wonder? 😕

Oh I know where you’re coming from Neil and it’s gutting to find of all the brushes you’ve got on your van the pair you need just ain’t there! 🙁

Then do take a closer look as very often the copper/bronze housing gets burnt up and damaged. 😉

It’s a bodge Neil no matter how you wish to describe it, it’s still a BODGE. And perhaps you may have overlooked the specific compound a carbon brush is made up of? The hardness level varies from motor to motor as does the laminations some brushes incorporate.

You mentioned Candy and Indesit? Now what similarity do their motor brushes have I wonder? I have 4 different Candy brushes on my van and no way do the carbons have any size, shape or potential hardness compatibily to Indesit brushes, they don’t!

And what about the springs eh? The springs are subjected to a degree of heat levels that eventually wear them down as well. For example, a 7 year old Candy’s brushes are well knacked by the time they need replacing but cobbling a new brush into a tired housing and a clapped out spring is not an option, is it, what do you reckon?

I repeat, it’s a bodge, a cop-out to get you out of trouble, a first fix call-out charge, job done….yeah right. :rolls: And if you get a recall next week on the job, then what?….I wonder?

How many brushes have you soldered into Bosch brush rings Martin i wonder?

The fact is that wear to the holders can be easily ascertained by inspection and feel with a new brush in place…something i do as a matter of course when swapping brushes within holders and i have to say the number of holders i’ve condemned is very very few.

As to being the wrong grade or compound of carbon, yes you have a point but if it means the brush will last only six years instead of eight well quite frankly i can live with that, and so do my customers.

The springs do suffer from the heat sometimes and in those situations i can usually find another spring to replace the original.

On the whole Martin, yes i’d rather fit a new holder and brush every time, but to replace the brush alone can be and is a perfectly acceptable repair.

None!……..I’ve never ever managed it, the two types I tried fitting to the old end frame were a right old BODGE, so I never ever fitted one to a machine. I always but always replace with the genuine Bosch Motor End Housing complete. (They are all fitted with the new type brush holders anyway, very nice they are, proper job. 8) )
