Below normal circumstance, when we step on brake pedal brake, brake piece attrition undertakes with undercarriage of Buddhist templeput on the brakes below the function that separates pump piston in brake, have the effect of slow down speed. Brake piece only should attrition can have loss, it needs to change to just go according to using a case, and of undercarriage of Buddhist templeput on the brakes wear away should be less than brake piece, but need to change according to actual condition as much.
This also is a common sense, but still have one fraction car advocate do not understand, for instance the article will rise of respecting inferior K5 car advocate. Brake has abnormal knocking, master examination discovery is brake piece should change, when the car advocate see the master dismantles the lock below piece hind, say he drives more than 3 years, still do not know stop a machine by cutting off the power piece still need to change, this lets a master feel a bit helpless.
Original, car advocate drive will repair a factory is to should maintain engine, the issue that examines brake abnormal knocking incidentally has detailed examination to whole vehicle. The master is maintaining when engine, the ageing of dynamo leather belt that discovers it again is very serious, have a lot of flaw, following graph arrowhead place are shown, such leather belt needs to change in time to just go.
Because the travel course of development of the car is more, the master gives sparkplug tear open come down to check, with fire prevention beautiful stuff has a problem. Place of arrowhead of green laying a plan is shown, this is the 4 ignition coil of engine, without the problem, below is 4 sparkplug. When we are seeing the stand or fall of sparkplug, the central electrode that basically visits green area namely, side electrode and ignition clearance, these 4 sparkplug do not have a problem.
After the problem of engine is checked, the master discovers turn off a machine piece had been about to reach wear limit. Place of area of orange laying a plan is shown, brake piece ply is very thin; Green arrowhead place is shown, this iron piece is brake piece call the police piece, when brake piece wear away when ply obtains this position, step on brake to be able to appear very acerb abnormal knocking. ?
Car advocate explain in what listened to a master hind, agree to change at once brake piece. Place of arrowhead of green laying a plan is shown, this is new turn off a machine piece ply; Orange arrowhead place is shown, old turn off a machine piece already very thin! ?
This rises inferior the travel course of development of K5 has exceeded 110 thousand kilometer, undercarriage of its Buddhist templeput on the brakes wears away a bit serious also, following graph arrowhead place are shown, brim of undercarriage of Buddhist templeput on the brakes has very deep edge, if incorrect brake piece or if undercarriage of Buddhist templeput on the brakes undertakes handling, new turn off a machine piece there still can be abnormal knocking after installation. ?
So, brake piece or how should be undercarriage of Buddhist templeput on the brakes handled? The master expresses, the simplest way is a brake piece the brim undertakes burnish, allow turn off a machine piece the brim forms a radian, can contact closely with undercarriage of Buddhist templeput on the brakes so.
Still having a kind of idea is to Buddhist templeput on the brakes undercarriage undertakes simple burnish, specific how should burnish see what undercarriage of Buddhist templeput on the brakes sets change how much is ply. Place of area of green laying a plan is shown, the MIN above states undercarriage of Buddhist templeput on the brakes is the thinnest ply, 24.4MM states undercarriage of Buddhist templeput on the brakes is about to change to 24.4 millimeter.
After the master is measured with special apparatus, the ply that discovers undercarriage of old Buddhist templeput on the brakes still can undertake comprehensive burnish, in course car advocate undercarriage of boring Buddhist templeput on the brakes begins after agreeing. ? Following graph arrowhead place are shown, boring dish.
The master used 20 minutes or so, dish good to boring, the case that place of following graph green arrowhead show. And orange arrowhead place is shown, this is undercarriage of another Buddhist templeput on the brakes, be about next boring it. ?
Master undercarriage of two Buddhist templeput on the brakes after boring is good, undertake burnish with fine sand paper again, mix later new turn off a machine piece an installation checks to the car, brake walks to won't have appeared in test-drive road abnormal knocking. This is master maintenance rises inferior the process of abnormal knocking, it is brake piece and the problem of undercarriage of Buddhist templeput on the brakes, very simple, it is good that car friend understands simply.
