Brake fluid Top Off
« on: April 04, 2019, 02:37:03 AM »
My front brake reservoir is at the "min" level.  I have scanned some posts about the front brake fluid bleeding process.  What I want to know is if I can just top-off if I am under 6k miles.  Or do you always have to completely replace / bleed?

Check your pads make sure they don't need replacing. Then check for leaks. Then top off.

Ah ok.  Brakes do seem slightly less grippy.

Preferred fluids?

Don't top up the fluid if your pads need replacing as it will then be overfull.  Check the pads, replace if necessary then check your fluid level.  Brake fluid doesn't evaporate, so low fluid usually means the pads are getting low or you have a leak (which is unusual).  As the pads wear, the pistons are out further to keep the pads in contact with the disk hence the low fluid level

Brand name DOT4 fluid. Motul is 5.1 and that number is confusing as you do not want to ever use DOT5 fluid in the system. As mentioned I bet your pads are pretty thin. If you ever top up, remember to remove some before  installing new pads or it will over flow. 6000 miles is time for the first brake fluid change. Then yearly after that if you want to keep things from getting nasty. Keep a spray bottle of water and a couple of drops of dish soap handy to wipe up any spills right away.

Change pads first, then manage fluid levels. Even then it doesn't take rocket science to bleed the system a bit especially at the MC.

  :460: If you go the other way round...top up then new pads, compressing the pistons to change pads will probably result in fluid overflow. Pads are relatively easy/cheap repair. If you inspect them, I'm sure you'll find they're ready for a swap.
