vibration when braking at high speed

[gambit5]

na encounter nyo na ba sa kahit anong mitsubishi model yung nakakaramdam ng vibration sa brake pedal kapag nag bebrake during high speed.... say speedo reading is 120 kph and ur trying to slow down by pressing on the brake pedal.....

sabi kc ng officemate ko....lahat daw na na drive nyang mitsu....

galant, lancer tsaka strada eh ganon yung experience at high speed braking...

[marwen]

???? nope

[Ungas]

That symptom is prone to brake drum setups at the rear due to improper or unbalanced rear pad wear. Just sand the thicker part to equalize it from the other side. Its usually the lower part of the pads that are thicker than the upper portion.

[pajerokid]

Pwede rin improper setting of the front bearings. or the lack of brake pad shims. shiyet! wala akong shim dun sa isang preno ko!

[Bubbles]

Iba pa ba yun sa ABS system? kasi yung feildmaster ng prend ko, nagpupump yung pedal. ewan kung yunyung sinasabi mo. kung hindi ABS equipped, wala naman ako nararamdaman. I have a galant and a pajero. yung may ABS nag pupulse, kakatakot nga yung ABS eh. parang ayaw huminto

[OTEP]

Could also be due to warped brake rotors.

[Bubbles]

yup, pag warped na and discs, hindi even ang pagslowdown. mafefeel mo yun pag bagal na takbo. kakapit tapos luluwag tapos kakapit...

[pajerokid]

ABS pumping would only be felt upon emergency braking. besides, sabi sa title all mitsu vehicles. lately lang naglabas ng abs ang mistu locally. (in relative terms)

sori di ko na update yung thread....

yung ride ko na 2002 adventure, inamin ng QC Diamond motors na me problema yung disc rotor ( after their own test drive sa north expressway ) - pinalitan nila ng libre yung dalawang disc rotor ( still on warranty ) ....

napansin ko lang...yung original disc rotor, me mga concentric circles na, nung pinalitan ng bago, smooth yung surface tapos after a few usage ( ngayon ), me concentric circles na uli.....normal ba yun ?


last week nagpunta kami sa baguio, on our way back, ang ganda na ng kalsada d2 sa entrance after angeles, we did 120 - 130 kph tapos ni try ko mag brake uli ....ganon pa din....lumalababan sa paa ko yung brake pedal - me vibration pa rin ---- hindi naman equip with ABS yung adventure.....


thanks sir ungas, baka e check ko this weekend yung rear drum brake naman --- sana duon yung problema .....

[Jeepcruizerph]

na experience ko na rin sa crosswind yan, 100-120kph sabay break...mag pupump yung break pedal or vibrate... bagong labas pa yung xwind ko nito nung napansin ko sya...di naman alam sa casa lol... up to now mayroon parin

sa ABS naman oo daw sabi ng pisan ko mararamdaman mo...kala nga ng pisan ko naka abs ang xwind hehe lols

[gambit5]

na try ko sa Revo ng brother ko before.....wala syang ganun eh.... kaya pinag ddisketahan ko ng me defect yung adventure ko....... kahit nung brand new pa sya....nirereklamo ko na sa casa yun....

una, ne resurface nila yung rotor disc......... meron pa rin.....

2nd, ne resurface uli on next PM visit ....... meron pa rin.....

3rd, pinalitan na...... meron pa rin ngayon....

kaya ang tanong ko.... na experience din ba eto sa pajero ?

o kaya sa mga kombinasyon front disc brake/rear drum brake ?

[woodfire]

Yup. naexperience ko ito sa pajero. they say its the rotors but i still have not replaced them baka mali ang diagnosis.

[roydok]

So far wala itong symptom na ito in my Strada.

[jackaroo]

If the "circles" on the rotor are deep then your brake pads are too hard- change to a softer compound, like bendix 4x4 model.

[pajerokid]

gambit, said cocentric circles are normal as long as they are not deep. Touch the rotors, pag malalim tlaga, then its definitely not normal. dapat smooth to the touch.

sometimes vibration during braking the culprit is not only the brakes. others are not well balanced tire, worn steering components, bearings not properly tightened, uneven tire wear. This happened once sa prado ng friend ko, checked the brakes na, changed the pads, balanced the tires again, resurfaced the rotor. the culprit is the rubber bushings holding the steering rack and pinion.

[Field Master]

By the way, is the Pajero Gen 2.5 (2000 model) equipped with ABS? Tanong ko lang kasi hindi ko yata nakikita ito as safety features i read from mits paj manual and brochure. I have not noticed it too when I have my brake serviced during the weekend.

I experienced vibration too (jerky) when brake is applied especially when my ride is steeping downhill. What the mechanic found is that my left rear brake pad stucked-up causing surface damage on my rotor. I have all the 4 wheel pad replaced, 1 rotor resurfaced and 1 broken brake assembly nut replaced (medyo mahal po ang turnilyong ito P900). Now I feel the improvement in terms of smooth and immediate brake response.

Paki sagot lang un tanong ko na kung may abs ang 2000 model na Pajero ha.

[pajerokid]

Wala sir.

Yung manuals po natin kasi galing Japan so some of the features listed there are either optional or not available in the local release.

Yup, there are a zillion reasons why your car would be vibrating under hard braking from 120km/h... and poor alignment or balance should be the first thing you tackle.

I haven't experienced it. Baka naman engine vibrations lang. Anong tawag uli doon? Yung sobrang baba ng rev tapos naka 5th gear pa rin..I forgot the term..
