1. apply the brake is in charge of (if contact is in) leakage or block, brake fluid is insufficient, oil pressure of apply the brake drops and be out of order. Answer to check pipeline of apply the brake regularly, eliminate leakage, add pipeline of brake fluid, dredge.
Air is entered to make apply the brake logy inside canal of 2. apply the brake, be heated of pipeline of apply the brake, leftover pressure is too little inside the canal, cause brake fluid aerification, bleb appears inside pipeline. Because gas is compressible, bring about moment of force of apply the brake to drop when apply the brake consequently. When safeguarding, can divide apply the brake platoon of the air inside pump and canal to add sufficient brake fluid completely.
Clearance of 3. apply the brake is undeserved. Apply the brake grinds a working face and the gap that apply the brake rouses wall working face are too big, distance of piston of pump of time of apply the brake is too great, apply the brake of as a result moment of force of logy, apply the brake drops. When maintenance, move space of school apply the brake in the round by the standard, move ratchet from high speed Kong Bo with crop screwdriver namely, stretch hoof of apply the brake completely, clearance is eliminated, age 3~6 of ratchet go back next, in order to receive a normative clearance.
Beat of 4. apply the brake and grind line piece the contact is undesirable, brake shoe is out of shape or circularity of beat of apply the brake exceeds 0.5mm above, bring about grind line piece as undesirable as contact of beat of apply the brake, friction of apply the brake rules falls. If discover this phenomenon, must boring or school make repair. The diameter after apply the brake rouses boring must not be more than 220mm, should change otherwise new.
5. apply the brake grinds piece by oily dirty pollution or soggy be affected with damp be affected with damp, grind coefficient is reduced quickly, cause malfunction of apply the brake. When safeguarding, tear open next friction piece clean with benzine, heat blowtorch roast, make infiltration piece medium oily ooze comes out, when ooze oil is punished severely, must change new piece. To soggy friction piece, usable and successive apply the brake makes with producing heat energy water evaporates, restore its to grind coefficient can.
Bowl of skin of total pump of 6. apply the brake, cent pump (or other) attaint, pipeline of apply the brake cannot generate necessary internal pressure, ooze of oily fluid leakage, cause apply the brake undesirable. Answer to tear open bowl of skin of total pump of check apply the brake, cent pump in time, change abrasion attaint component.
