8.3.    

BRAKE BLEEDING PROCEDURE

 

‰

  

WARNING!

 Familiarise yourself with the hazards of brake fluid - read manufacturer’s instructions on the container.

8.3.1.   

IMPORTANT: DO NOT

 touch the vehicle’s brake pedal whilst bleeding the brakes.

8.3.2. 

  

Refer to the specific vehicle manufacturer’s instructions for brake bleeding and wheel sequence procedure before proceeding. If no 

 

specific instructions from the vehicle manufacturer exist, follow the instructions detailed below.

8.3.3. 

  

Remove the cap of the vehicle’s master brake fluid reservoir. If the fluid level is not at maximum, top it up. 

8.3.4. 

  

Attach the appropriate size bleeding attachment to the bleed nipple on the brake calliper of the first wheel, normally nearest to master  

 

brake fluid reservoir (fig.15).

8.3.5. 

  

Operate vacuum pump until approximately 21inHg vacuum is created.

8.3.6. 

  

Apply copper grease to the brake bleeding nipples before and after the brake bleeding procedure to reduce the possibility of seized or  

 

broken nipples when the brakes are next bled.

8.3.7. 

  

Open the bleed nipple about a quarter of a turn. Allow brake fluid to be drawn until no air bubbles are visible in the brake fluid in the   

 

clear hose.

8.3.8. 

  

Tighten the bleed nipple.

8.3.9. 

  

Remove the attachment from the brake nipple.

8.3.10.  Repeat the process as necessary.

 

NOTE!

 Check the master brake fluid reservoir regularly to ensure that  

 

the level does not drop too far, and top up as necessary.

 

NOTE! 

Empty bleeder container regularly and 

DO NOT

 allow  

 

container to overfill as brake fluid will be drawn into vacuum pump. 

 

‰

   WARNING! When brake bleeding and/or fluid changing is  

  complete, test the action of the brake pedal to ensure that the  

  brakes are working before attempting to drive the vehicle on the  

  road and test the vehicle for satisfactory performance of the  

  braking system. 

8.4.    

CLUTCH BLEEDING PROCEDURE

8.4.1. 

  

Refer to the relevant vehicle manufacturer’s instructions for clutch  

 

bleeding procedure. If no specific instructions from the vehicle  

 

manufacturer exist, follow the same basic procedure as the brake  

 

bleeding instructions above.
