to clarify.
Charge cooler pumps are available as overhauled units starting from £135, there is an additional £155 if you require a pump with a rewound armateur, new commutator and brushes.
if i was to charge by the amount of time it takes to get the pumps looking and working like they do i would charge treble the amount i do!
I have proven time and time again replacing just bearings is not a fix that will last long, the same can be said for replacing just brushes, FACT
Brushes as short as the ones shown above will mean the commutator is VERY worn and running on borrowed time
it won't last running for very long as there will be very little copper left.
shown below is a rewound Armateur, new Comm and brushes (different brushes are used these days)
A small part of my collection of worn Armateurs, these will be having new Comms fitted and would NEVER be reused as is.
the above Armateurs are from pumps that threw error codes or where people butchered the pumps trying to change bearings with screwdrivers...
As the brushes wear down they fill the pump housing with carbon dust and speed the whole wearing process up, short brushes create a lot of heat and agin do nothing for the life of the pumps.
i suspect the pump is not working at its best, how many miles/K's has your car done!?
