Balik ulit and vibrating brake pedal problem ko...

[deedee91874]

mga sirs meron din ganyan ung mazda mpv ko. pag inapakan mo parang my tumutulak pabalik nung brake pedal. pero ang naiisip ko is baka epekto ito ng abs pero just to be safe check ko din ang mga rotors at brakepad.

Pencils: Yup I agree on your points about the DS being the culprit. I don't feel naman any vibration on the body nor on the transmission when the car is in motion. I'm bringing my car to big berts this coming sunday morning together with my mechanics since Dave there has a good lifter and has graciously accomodated my request if I could borrow it for a couple of hours.

The vibration that I feel on my brake pedal isn't the pulsatile-like kind of vibration. It just feels like as if you could feel the turns of the rotor being transmitted to the pedal itself.

Philip, san ka nagpa repack ng bearings? kasi meron din problem ang vitara ko pero medyo iba ng konti. when im driving the highway in 90kph to 100kph, my car wiggles in upward and sideway motion but in a tolerable manner. Pero pag lumagpas na sya sa 100kph eh nawawala naman. I already had a wheel balancing, wheel alignment, new set of tires, new tire rods and also installed the steering dampers, but still the vibration persists. Dunno what to do next? Help naman guys...

Di kaya sa drive shaft or wheel bearings? San ba maganda mag pa check and yung mura na magaling.

wiretap: saw you kanina sa emergency shoulder ng SLEX after alabang exit. Hope it's not the vibrating pedal

garyq: I was on my way to Batangas. Suffered a tire puncture right after the Alabang bridge!!! Bad trip talaga. I think my KO's stepped on a medium-sized nail that punctured the whole tire thread and got dislodged. I was driving around 50kph when I heard a soft boom coming from the back. Had to do a tire change there.

mikaztro::: Yung symptoms ng sasakyan nyo po ay malamang sa unbalanced tires. Minsan di nakukuha ng balancer sa isang sukat. Try other balancing shops, and have it checked twice.

Just came from Bigberts. Vincent was very gracious enough as to allow me use of their lifter. My friend Alan who owns a Vitara also was there to do servicing din. Had my Zuk lifted then I had the rear tires spinned. Felt the vibration so definitely the cause was from the rear drivetrain. Palit kami brake drums with my friend. I installed his drums in mine then test drive. Ayun! Nawala ang vibra. Install ko din brake drums ko sa kanya. Sus...nag vibra din brake pedal niya. Conclusion: Warped rear brake drums.

My next move: either to get a new set of rear brake drums or ibalik ko yung drums where I had it refaced before and have it done again.

gud na solve din yung problema

I was also going to Sto.Tomas, Batangas when I spotted you.

Congrats Doc Phil!

At least na-isolate na yung prob. As stated somewhere in The Worksop, drums can also warp and cause vibrations.

Oh, and just a suggestion. Replace them rather than reface them

mikaztro, subukan mo muna ilipat yung rear tires so front, di ba ganyan yung nangyari dati sa akin......I tried balancing but no good.... but when I put the front tires to the rear ayun nawala na..

[wiretap_md]

Had my rear drums refaced again this afternoonat the same machine shop that initially did it para wala na added gastos pa. They admitted may konti pa natirang uneveness. Just makes me wonder why they didn't detect it during the first time. Anyway, everythings smooth now. Will continue to observe it. Thanks guys for all your inputs.

pajerokid: Opted to have them re-refaced nalang kasi ang mahal ng rear brake drum para sa Vitara. P5240 original. Wala pang replacement. Huhuhu. Imagine spending more than P10k just to replace both.

Philip, Have them replaced na lang rather than reface. Baka Di rin ma perfect yun pagkaka reface. Replace them with brand new ones or surplus.

Mike, Have you checked your Propeller Drive Shaft or Cross joints? Lift your car and inspect by turning your rear wheels. The Propeller should be straight and free from dent or clinging dirt or undercoating paints.

since you guys mention it, i use our vitara today, mdyo feel nga yung surface ng rotors sa pedal pero acceptable naman, di ba ganon sa lahat ng vehicles?

[wiretap_md]

"Acceptable" is a relative term and very subjective depending on the driver's feel. I am particular with the vibration because it is noticeable pero a bit lang (rate ko 2-3/10). I'm sure OTEP would bash me again for being oc-oc. Hahaha. One thing that was driving me was that I was curious as to what was causing it. I'm glad I finally did. I wasn't ready to spend another P10k for drums kasi baka ma warp lang sa next offroad so might as well stick to my old ones and reface nalang ulit since I paid for the refacing already anyway.
