Extra brake oil :(
Hi, I bought my Grandsport with 6000 km. Now, at 7000 km I needed to switch my front brake pads. I didn't check the brake oil before switching the pads; however, after putting in the new ones I noticed that the brake oil level is above the max line. Should I take some out or is it o.k. to leave it that high? The brake oil reservoir is very little and I am worried that when tracking the car and the fluid gets hot it might find it's way out through the cap. Thanks

Thanks for the reply. Why would I need to bleed the calipers if I only changed the pads? I didn't "crack" the hydraulic system.

If the reservoir was originally at the max mark when the car was new why after putting on new pads would the oil level be higher?

A turkey baster works great for removing the excess fluid, just be careful as brake fluid eats thru paint so take extra care to not spill any!
I would bleed the brakes too, because over time brake fluid absorbs water which lowers its boiling point. This makes the fluid easier to cook which leads to air bubbles getting into the system and then you get brake fade. Its generally just considered good maintenance to bleed the brakes when switching pads.

Rather than a turkey baster that drips, go to Tractor Supply and get a 40cc syringe W/o the needles. You can remove the correct amount with no drips. They are on the order of 2-3 for a buck, so cheaper than a Walmart turkey baster. I keep several in my tool box and throw them away when done.
Also, best not to fill to the MAX at all. The system is a closed system, and if you heat up your brakes and fluid enough, you can pressurize the system can lock the brakes up. There have been several instances we've seen at the track where the owner (usually a NOOB) has the dealer do maintenance and the dealer fills to the max. Then after a session on the track, they come in with smokin' brakes.
I always fill just to the seam. That is plenty of fluid in the reservoir. Then as your pads wear add just a little bit.
