When a garage ,either independent or main dealer, changes the brake fluid, do they drain completely or just undo the bleed valve a little and then top up.?

last thing you need is air in there   so remove old from res' --  refill---then blow or suck thro'  

What exactly does a dealer mechanic do,does he just removes a bit from each caliper bleed valve and tops up the reservoir, or does he completely empty the whole system and refills and bleeds the system. What about the ABS system, does that get emptied and refilled.

I wouldn't expect a garage to completely drain the brake system.

 

Standard practise is to keep taking fluid out of the calipers until the new stuff comes through, obviously keeping the brake fluid reservoir topped up with new fluid. This can be done by either colour of the fluid or by flushing an amount as specified by the manufacturer through.

 

This will flush some of the fluid in the ABS pump but probably not all of it. If you really want to be sure, the pump can be cycled with VCDS and then more fluid flushed through.

Is that the 'normal' service you would get from a Skoda Dealer.

I think a dealer would normally do the full flush. I'd only really expect the ABS pump to be cycled when it's been replaced or there has been air in the system.

 

Only way to be sure is to ask your dealer...

 

Are you having a problem?

If charged for a Brake Fluid Change the Brake Fluid should be changed, if you are paying for that anything less is fraud.

 

You can buy a kit and check your Brake Fluid for H20 content, then maybe not change the fluid first at 3 years then every 2.

Even put in better brake fluid than the OEM / Main Dealer supplied Brake Fluid.

No, just want to know what to expect, not sure to go to a local garage or dealer.

Either should be fine, your dealer might also be happy to price match an independent using genuine VAG fluid

Thank you all for your input, I'll let you know the outcome.
