2888499 - X20 BRAKE FLUID LEAKS

A brake fluid leak is seen.

		Results of the tests
0	PRELIMINARY CHECKS	All OK	Problems met	Operation
	Check whether the fault is accompanied by decreased braking efficiencyVisually inspect the brake fluid level in the reservoir Op.   3330A10	Continue to Step 1	Decreased braking efficiency	See table   F01
			Level too low	Restore the correct level and carry out a road test. If the defect persists, Continue to Step 1
1	RESERVOIR LEAKAGE TEST	All OK	Problems met	Operation
	Visually check that there are no leaks from the reservoir and the pipes	Continue to Step 2	Leaks from the pipes in the area of the reservoir	Tighten the pipes
			Leaks from the reservoir	Replace the reservoir Op.   3330C34
2	PUMP LEAKAGE TEST	All OK	Problems met	Operation
	Visually check that there are no leaks of fluid from the brake pump and connectors	Continue to Step 3	Leaks from the connectors in the area of the pump / ABS control unit	Tighten the connectors or replace the damaged parts (see Assembly 3340B)
			Leaks from the pump	Replace the brake servo assembly Op.   3330D10
3	CHECK HOSES	All OK	Problems met	Operation
	Visually inspect that there are no leaks from the hoses	Continue to Step 4	Leaks from the connectors or hoses deteriorated	Tighten the connectors or replace the hoses involved (see Assembly 3340B)
4	RIGID PIPES CHECK	All OK	Problems met	Operation
	Visually inspect that there are no leaks from the underbody rigid pipes	Continue to Step 5	Leaks from the connectors or rigid pipes damaged	Tighten the connectors or replace the rigid pipes (see Assembly 3340B)
5	CHECKING CORRECT OPERATION	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	Fault persists	Search for the fault starting from another symptom'
