Miniature carApply the brakeThe system is common breakdown and overhaul method:

One, noise of apply the brake

1, beat of apply the brake breaks a circle its circularity error exceeds 0.5mm, working face of beat of apply the brake is out of shape 9 elliptical) , grind when apply the brake piece with joint of beat of apply the brake instantaneous happening collides, give out acuteness at the same time bump noise. SafeguardWhen, tear open beat of next apply the brake, undertake boring by normative standard, need to undertake balancing function desired result, lopsided capacity control is in 200g.cm.

2, apply the brake grinds a surface is too slick, grind when coefficient is small and pressure of apply the brake is great, slick surface is slippery when grinding, arise grind noise. Or grinding deputy between a place of strategic importance entered eyewinker extruding to grind the surface, also can appear from this grind noise. Beat of next apply the brake are torn open when maintenance, cleared eyewinker chafes with burnish of thick sand paper piece, make cooperate to grind deputy contact area amounts to 70% above can.

3, apply the brake grinds piece wear away badly, exterior occurrence groove reachs irregular figure, cannot mix effectively when apply the brake apply the brake rouses joint, or apply the brake raises palm board to be out of shape, destroyed beat and piece coaxial is spent, local grind, collide and appear noise. When maintenance, should change grind piece, gripper shoe of corrective apply the brake.

4, attaint of front-wheel drive bearing, raceway and hole of hemp of ball surface emersion, groove even disintegrate, the apply the brake in travel can appearAbnormal knocking. Bearing of head of the axis before changing, can eliminate this noise.

2, apply the brake undesirable or malfunction

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.

2, air is entered to make apply the brake logy inside canal of 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.

3, clearance of 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, pump of time of apply the brake
