Pumupulso pa rin ang preno ko!help!!!

**miked** · October 27th, 2009 10:05 AM

Mga bossing,

Storytelling muna ako ha.
Before servicing: brake pedal ko e mejo pumupulso pero negligible.kung talagang "observant ang paa ko" e napapansin kong pumupulso. i repeat, negligible sa pakiramdam.hehe

After the servicing: tumindi na ang pagpulso. halos sasabay na rin ang puso ko dahil kumakapit then nawawala then kakapit and so on ang preno.

what could be the problem? nakakailan nako sa adjustment sa brake drum pero hindi matanggal ang pagpulso.

eto ginawa sa pipip ko. nga pala pipip ko e mighty max na 4d56t auto. yung dati pa rin ang brake lines.
1. reface disc rotor (left front lang kasi ok p ung right front)
2. palit ng flexi hoses kasi may tagas na
3. pinantay rin ung brake pads sa calipers
4. linis preno sa harap at likod.
5. palit rubber cap at boot sa left rear.
6. sangkatutak na "bleeding operation"

TULONG PO!

Have your other rotor resurfaced also it could be uneven which is causing the pulsing. What do you mean by number 3? Did they put new pads or just used the same old pads?

regarding no. 3, yung brake pad kasi sumunod na sa contour ng disc rotor kaya pinantay ko boss. antagal nga ng pagliliha ko e.kapagod.cguro nga ung kabilang disc rotor. nxt time na lang at naubos na pera. by next payday uli.huhu. ang sabi naman ng kakilala kong mekaniko e baka raw hindi na perfect circle ung brake drum sa likod. ganun ba kadali ma-"oblong" ang brake drum? i think hinde. kasi ininspect ko wala naman. salamat sa reply boss

Ok. I have never done that with brake pads, usually if I have it resurfaced I put new pads and not reuse the pads. If you are reusing the pads it could be the pads causing it also since you mentioned having the pulsation get worst.

cge mga boss,

noted lahat. subject to availability of funds pa ang palit pads at rotor. i'm planning din kasi na bumili ng disc rotor kasi manipis na yung isang side sa left front. sa surplusan na lng siguro. ok lang naman na isang disc rotor palitan di ba mga boss? salamat sa mga impormasyon

there could be a problem with the mastevac/hydrovac. Check the vacuum lines and the mastervac for proper operation. Did the mechanic who serviced the brakes removes the brake master cylinder from the hydrovac?

Save the money and change it as a pair instead of just one.

chineck boss ung linya. sa hydrovac naman chineck din by starting the engine, pressing the pedal then shut off engine.bumabalik naman kapag pinatay makina. im not that very observant with regards sa resistance ng pedal pagkapatay makina. last year lang napalitan ung master cylinder on the same hydrovac.
salamat

yup. noted boss. isasabay ko na rin ang front shock absorbers. i'm planning to buy KYB GR2 or gas-a-just. kasi sabi at par sa performance ng mga high end na shocks at relatively more affordable.
