nagbavibrate habang napreno

[RyanZeke]

mga master patulong naman..

ilang beses na ko nakapag pabonding at resurface ng mga drums ko pero di matanggal ang vibration pag namemreno ako at highspeed nakakatakot tuloy gamitin van ko..

any tips mga master kung pano mawawala yun??

RyanZeke,
what is your make, model and year of the vehicle? check the brake rotors too for warpage, runout and parallelism. don't forget about the wheel bearings, they too can cause wheel shimmy. assuming the tires are balanced and no defects, i.e.; out of round, warped or has flat spots and properly inflated, then you can check for the brakes. try rotating the tires this way: RF to LR, RR to RF, LF to RR and LR to LF. try the process of elimination. most shops don't have wheel spinners to check tire defects, wheel bearing noise and imbalance while the vehicle is in the shop supported by jack stands.

boss ryan,

ganyan din preno hanggang ngayon. pinareface ko lng kasi isang disc. ayun lalu pang tumindi yung vibrations while braking kasi yung isang disc mejo warped na rin. planning to change disc and pads nako by next week. pinacheck ko rin wheel bearings at yung castle nut na naghohold sa mga bearings mejo maluwag..pinarepack ko na lahat. inform kita kung ano mangyari after the parts replacement

miked,
all brake discs or rotors have a minimum thickness marking on them. sometimes embossed, sometimes engraved or stenciled. if this minimum thickness is not met, and the rotor is thinner than minimum, the rotor warps from heat. thin rotors tend to get hot easier too.

mga tsips,

San pinaka mura magpa reface ng rotors sa qc area? Nag wiggle din ang manibela pag nag brake ako at 80 km/h up ang takbo. Gaano katagal ginagawa ito? sabi sa isang thread, kelangan daw yung di ordinaryo na machine lathe ang gamit kundi brake lathe (double bit).

Salamat!

hmmm, i think its much better to replace the rotors than to have it replaced. having it refaced, as like what jick said, would depend on the thickness of the rotors, and is not a guarantee that it will be ok after the reface.

mga sir toyota hi-ace commuter po ung sasakyan ko drumbrakes lang po sya..twice na po resurfaced nung 2009 di naman po sya warped nagpalit na din po ko ng mga pads nya kaso ganun pa din tlga...

you have four wheel drum brakes? when the drums were resurfaced, did the sound of machining change pitch just like chirp chirp or scrape---scrape---scrape? were the drums washed with warm soapy water after machining? were the hands of your "mechanic" or techinician clean avoiding oil contamination on the friction surfaces? check the wheel bearings too, they cause the same condition if they are bad

Mga Tsips,

Sorry sa late response. Just had 40k clocked on odo, di pa siguro due para palitan ang rotors.

Pag nag brake at 140k grabe ang wiggling. Tried braking hard several times nung byahe ako probinsya to even out the rotors mimicking the lathe machine. pero ganun pa rin.

Meron ba magaling at mura magpa reface ng rotors sa qc area?

TIA

Nagpareface ako last week sa Servitek Congressional Ave. P950 dalawa na siya sa front disc brakes.

Kung wiggling problema mo check mo rin lahat na pangilalim na suspension mo.

ganun pa rin preno ko. may pulsation pa rin. i tried to change the disc rotors last december pero ang biggest problem ko e wala ako mahanap na replacement for L200 na 6 stud. tried ung 6 stud disc rotor for isuzu trooper pero ayaw sumalpak. may difference na 5 mm. auto supplies na pinuntahan ko e ipamachine shop ko na lang daw. e sa tono nila e gusto lang makabenta.

mga boss baka may kilala kayo na nagbebenta disc rotor for L200?thanks

ganun din pajero ko.... patulong din.

pakikwento po yung story ng problem mu sir.

[deucewa]

tanong ko muna saan galing yung sasakyan mo? at ano ang nagbavibrate, yung preno lang ba o yung boung sasakyan? sabi mo kc pag high speed, baka biglang preno ginagawa mo? Sa amin may tinatawag kaming ABS (anti breaking system ata). pag mayroon nito, ang sasakyan mo, normal lang to. pag d kaya maihinto ang sasakyan gumagana to, kaya nagbavibrate, kusang gumagana. kaya bago ka magpagawa tingnan mo muna kung may ABS sasakyan mo. salamat

[Dudee]

pakikwento po yung story ng problem mu sir.

everytime magbreak ako, may sugsog ang pajero ko, at the brake pedal seems to have some resistance (umaangat). Mechanic said baka brake pad at lining daw.

I'm still in the process of diagnosing my PS steering and gearbox. anyone knows who to diagnose kung sira? Thanks

[miked]

i suspect yung sakin e out of round yung drum brakes. tried engaging the handbrake then depressed the pedal, ganun pa rin yung vibrations. i having some bad vibrations, you know! naks.

[RyanZeke]

ganun p din mga sir preno ko wlang improvement and worst pag cold engine wla ako brake kailangan pa bombahin ung preno pero pag nagkapressure na dikit naman ung preno parang hindi na nabalik ung brake piston dun sa rear wheel at para ding indi nababawasan ang air pressure sa hvac habang namemreno ka lalo pa syang napapump..kya medyo alalay lang ako sa preno..ngayon inspect ko ung hvac pati hoses..

[Howard Roark]

my problem was finally solved!

my car had warped front brake rotors. I have had them refaced, ayun, solved ang problema.

Fyi nung nagtatanong sa taas, may abs sasakyan ko, nangnginig manibela damay buong sasakyan pag nag brake at high speed. Had assumptions its either the brake caliper is loose, rotors warped, support for the wheels were loose. Good thing i researched about altis' problems and through the help of this forum, I was able to pinpoint the culprit.

Salamat mga tsips!
