Vibrating Brake Pedal

[ize_9]

Guys! Tanong ko lang whats wrong with my Lancer Gli. Ngayong ko lang kc na experience ito. I feel Vibrations when i step at the brake to malakas sya pag mabilis ang takbo ko so that puts my gear to the third o fourth. Ano kaya problema nito? Is there something wrong with my Brakes or something else? worried kc ako because i normally use the car to travel long distances so i need to have peace of mind kc kung serious ang problema got to bring it na to my mechanic. Guys hope to get your inputs.

There's a possibility that you have warped rotors.

if it's the rotors, have it checked, reface if needed or replaced if necessary. it goes without saying you need new brake pads when you have your rotors refaced.

kung okay naman ang rotors, baka uneven wear ng brake pads, or hangin sa brake system (not sure on this one).

sir artopogi is right...warped na yung rotors mo...
or pwede din yung drum brakes mo....nangyari na
yan sa revo namin..oblong yung drum brake..

[ian_rex]

check if there is even wear on the friction materials, or even the rotor surface. if the rotor surface is uneven, it can be grinded to even out the rough edges. the cause of this was the stuck calipers (kapag na baha ka, most likely ganon ang after-effect).

warped rotors or if you have ABS that is mulfuntioning could also do that.

............or it could be just a simple case of wheel balancing

[yebo]

sabi nya high speed daw e...

so pag high speed lang nangyayari, could be the abs. so ask ko kay ize_9, may sound ba na "dug-dug-dug" and the brake pedal "pumps" up and down? if your answer is yes then abs yan. pa-check mo sa mitsubishi service center, di yan kaya sa tabi-tabi na talyer lang.

[xpac]

ang alam ko walang abs lancer gli, if i'm correct most probably rotor ang problema. idaan mo na sa service center mahirap may problema sa brake system.

could be warped rotors. it's a simple job to reface them (if they are not at the minimum thickness yet)

[ian_rex]

i agree. just bring it to the qualified technician or mechanic. kami ang ginawa namin nuon e ni-liha lang. tiyagaan lang, i believe some one here might not agree... pero nagawa naman namin.

[orly_andico]

pwede iliha ang brake rotor? baka naman pwedeng i-dremel?
akala ko you need a milling machine to resurface a rotor properly..

[Ungas]

Ang nililiha brake pads and shoes. Para pumantay. Minsan pag hindi pantay and rear brake shoes, ito rin ang dahilan para mag vibrate. Lalo na madaling siksikan ng dumi ang front brake pads.

Sa machine shops dinadala ang brake rotors para mai-balance at bawasan ng lundo kung warped.

[ize_9]

ah ok thanks for all the inputs pa check ko na nga agad yung brakes ko this weekend.

[speedyfix]

liha is ok kung di pa malaki yung kain. pero you will never get it perfect. this should be reserved for the pads and drums lang and not the rotor. best to have it resurfaced sa machine shop parin.

[pajerokid]

Question. Could you actually feel the warpage with your fingertips?

[pajerokid]

So ano ang visible symptoms ng wapred pads? i mean, you cant just reface all four right?

[speedyfix]

yes you can feel the warping with your fingers. when may mga uneven spots or grooves then definitely kelangan na ipareface ito.

usually just the rotors yung nirereface while the pads are just sanded down to spec

[GoThicbLuE]

madali makita gamit ka ng alambre....
turn the rotor in the spindle with the wire slightly touching the rotor surface and slowly turn the rotor to see the gap between the wire wnd rotor become bigger or smaller

[CZintrclr]

almost same problem sa akin ito. Pero in my case this happens only on unpaved roads saka without me applying the brakes. check ko ang brake pedal mahigpit naman ang screws pero pag ginagalaw mo ng kamay may little movement siya left and right.
Paano ba ayusin ito? thanks

[woulfe27]

kakapareface ko lang ng rotors sa greasebee sa cainta. P320 each. merun silang machine dun na pangreface talaga ng flat surfaces.
