ALP 3 IDLING PROBLEMS (unstable idling)
RECOMMEND AT IONS Do not consult this diagnostic but before performing a complete
checking by means of the CLI P tester.
C heck if there is petrol in the fuel tank (fuel indicator failure)
C heck if the vehic le is supplied with adequate fuel
C heck tha t supply cir cuit hoses are not broken (espe cially further to a dismounting)
C heck the condition of the fuel filter
C heck the condition of the fuel tank
C heck that fuel tank aeration is taking place.
C heck the connection and the condition of the idling regulator connector.
Re place the connector if necessary.
C heck the motor of the idling regulator
In order to unblock it, you may slightly hit it.
Disconnect the connection hose between the canister purging valve and the intake manifold.
Cl amp the connection hose in order to stop the air passing.
If there are no more disturbances, the cause is the canister purging valve.
C heck the spark plugs and ignition coil condition
C heck tha t these eleme nts are specific to that vehicle.
C heck that the exhaust route is not clogged and the catalyst is not clogged.
Check, by means of the oil dipstick, that oil level is not too high.
C heck for lack of sealing at servo-brake (noise).
C heck the intake manifold condition
C heck if the valve body is not clogged
C heck the engine compressions.
C heck the engine flywheel condition
C heck the distribution setting on.
AFTER Perform a checking by means of the CLI P tester.

II. CONSTANT EFFECT AT BEHAVIOUR
EFFECTS
Brakes not accomplishing the required
b raking distance
Vibrating brakes
When braking, the vehicle ( front part)
is left/right deviating
Braking
Heating brakes POSSIBLE CAUSES
- Non-uniform worn brake linings (backing
off);
- Brake l inings slightly gr eased;
- Springs with modified characteristics.
- Brake disks with high wobbling;
- Inconstancy brake disks width;
- Particles abnormal deposit on brake disks
(oxidation between linings and disk).
- Front axle suspension, steering (to be
checked);
- Stuck piston;
- Tires – wear, inflation pressure;
- R igid duct narrowed (flattening).
- Stuck piston;
Automatic adjustment : hand brake cable very
tighten.
REMARK :
Automatic recovering is performed by
means of the brake pedal, if there is no ab-
no rm al t ensi on in the hand brake cable
when released (hand brake released).
- Return spring.
- Insufficient hydraulic stroke of the brake
pump, not allowing the return at rest of the
brake pump pistons ( brake pump remaining
under pressure);
- St uck pistons or hardly returning;
- R igid duct narrowed (flattening);
- Def ective adjustment of the hand brake
control.

30Brake fluid
PERIODIC CHANGE OF THE BREAK FLUID
The m anufacturing conception of t he brakes equipping t he Dacia vehicles especially the
ventilated disk brake, enable the maximum diminishing of the fluid vaporization, even in case of
intensive using of brakes (mountain area), due to good disk cooling.
The brake fluids, suffer in all cases a slight degradations during the use, by a slight humidity
absorption, that makes necessary the complete replacement after a period of time or after some
driving (4 years or 60,000 driven km)
COMPLETION OF THE BRAKE FLUID LEVEL
The wear of brakes pads and shoes, leads to a gradually diminution of brake fluid level in its
reservoir. It is useless to compensate this diminution, because the level will be restored when changing
the brake pads and shoes.
Obviously , in the meantime, the level of brake fluid in reservoir must not go down bellow the
MINI mark.
HOMOLOGATED BRAKE FLUIDS
The mixture in t he braking circuit of two non different brake fluids may leads to important
risks mainly due to gasket damage, incompatible with new fluid.
In order t o a void such risks, it is obligatory to use only bra ke fl uid re commended by the
producer, i.e. : SAEJ 1703, DOT 4.

Handbrake - adjustment
The adjustment of the handbrake shall be performed with the vehicle lift on a two-column
elevator. Note :
The adjustment i s obligatory performed anytime t he brake shoes or secondary cables
have been replaced.
Release the control lever of the hand brake (release position)
Tighten the nut ( 1) until the shoes lining come lightly into contact with the brake drum.
The adjustment shall be performed so that is insuring a hand brake lever stroke of min.12
teeth until the blocking of the wheels. Lower the vehicle from the elevator.
