This article mainly introduces how to perform brake exhaust operation on Isuzu vehicles
ISUZU IDSS MX2-T Diagnostic Adapter System Support G- IDSS/US-IDSS/E-IDSS (Included DHL Shipping)
Air in the brake hydraulic circuit will result in dangerous reduced braking efficiency.
The brake hydraulic circuit must be bled whenever the vehicle has been operated with the reservoir brake fluid level at an excessively low level or any time the brake pipes have been disconnected in the course of brake servicing.
The brake bleeding procedure requires the cooperative action of two men.
Brake Bleeding Procedure Bleed the brake hydraulic circuit in the following se- quence. LHD Left-hand rear wheel (vehicle equipped with ABS) → Right-hand rear wheel → DSPV or LSPV → (If so equipped) → Right-hand front wheel → Left-hand front wheel RHD Left-hand rear wheel (vehicle equipped with ABS) → Right-hand rear wheel → DSPV or LSPV (If so equipped) → Left-hand front wheel → Right-hand front wheel
1. Check to make sure that the service area is well ventilated. Apply the parking brake firmly. Start the engine and allow it to run until the vacuum pressure rises suf- ficiently.
Notice: Brake booster (master-vac) will be adversely effected if bleeding operation is performed without running engine. If the vehicle is equipped with ABS, be sure to remove the ABS fuse (60 A) from the fuse box before beginning the air bleeding procedure. If this is not done, air is not bled completely from ABS unit, so that ABS unit will be broken. (Be sure to install the ABS fuse (60 A) in speci- fied position when the air bleeding procedure is complet- ed.)
2. Fill the brake fluid reservoir (1) up to the “MAX” lev- el with clean brake fluid.
It may be necessary to replenish the brake fluid reservoir several times during the bleeding proce- dure to maintain the required level of brake fluid.
Notice: Pour the brake fluid carefully so as not to produce air bubbles. 3. Remove the right hand rear wheel cylinder (left hand rear wheel cylinder if ABS is equipped) bleed- er screw rubber cap and wipe it clean. 4. Connect one end of a vinyl tube (2) to the bleeder screw. 5. Insert the other end of the vinyl tube into a trans- parent container approximately 1/3 full of brake flu- id. 6. Depress the brake pedal (3) slowly 3 times and hold it depressed.
7. Loosen the bleeder screw (4) approximately 1/2 of a turn.
This will release the brake fluid with air bubbles into the transparent container (5).
9. Slowly release the brake pedal.
10. Replace the bleeder screw rubber cap.
Notice:
In order to bleed the air completely from the brake line, repeat the above procedures.
Bleeding of the brake fluid circuit should be performed for front wheel 10 times or more, for rear wheel 15 times or more.
11. Repeat Steps 3 through 10 for each bleeder screws as mentioned before.
12. After the air bleeding procedure is finished in all wheels, depress the brake pedal, and verify wheth-
04.2023 ISUZU E- IDSS Diagnostic Software Download and Installation Service
er there is no abnormality in operation of the brake system. 13. After the air bleeding procedure for individual wheel is completed, inspect the fluid level of the reservoir tank. If it is insufficient, replenish brake fluid. Do not overfill above “MAX” level. 14. Stop the engine.
