p38 brakes abit wierd!

hi everyone, this may be a silly question but i have been reading all these posts about the acumilators failing, and i had the three lights come on along with the pump running every time i brake, fitted a new acumilator and bled brakes, and seems fine,lights gone, brakes more responsive! but when i leave the car for a few hours or over night the fluid level creeps up well over the max mark! is this normal? thanks, Tom.

Yes.

When the pump runs the fluid level drops. The checking the level section in RAVE explains it.

After the pump stops the level slowly climbs again.

From RAVE:

FLUID LEVEL CHECK/TOP UP
1. Park vehicle on level ground.
2. Turn ignition ON, to activate hydraulic pump. If
pump does not operate depress brake pedal
several times until pump operates.
3. When pump stops, check level is between ’MIN’
and ’MAX’ marks.
WARNING: Clean reservoir body and filler
cap before removing cap. Use only fluid
from a sealed container.
4. If level is below ’MIN’ mark top up fluid level to
’MAX’ mark on reservoir, using correct fluid. See
LUBRICANTS, FLUIDS AND CAPACITIES,
Information.
DO NOT OVER FILL RESERVOIR
