brake drum problem

**markuz14** · December 12th, 2010 10:02 PM

mga bossing patulong ulit. yung right brake drum ko is pina rephase kasi sabi nung mekaniko is kinain daw yung brake pads nya kaya parang hindi na pantay sa loob... nagpalit din kami ng brake pads syempre... so naayos naman kaso ang naging problem is nuong tumagal (after a month siguro) parang mag tumutunog na parang "tog..tog...tog" nung una at napansin ko, out of curiosity kaya hinawakan ko yung mags ko is umiinit siya, mas mainit kaysa sa left mags ko... so dinala ko ulit siya sa mekaniko, inadjust niya po yung preno sa right brakes ko sa likod, pero after some time nuong check ko ulit e umiinit po ulit, naka 3 adjust (mga 2-6 weeks ang mga interval) na yung mekaniko pero after some time e umiinit pa rin. Question ko mga bossing e:

1. anu kaya posibleng sira niya or meron pa rin bang sira?...advise kasi sa akin ng mekaniko is bumili ng brake drum.
2. magkano kaya ang brake drum (for toyota revo glx) at saan nakakabili besides sa casa?

sorry po kung mahabang basahin... thanks in advance! Merry xmas!

usually kapag brake replacement eh sabay parati. ibig sabihin, kung sa likod dapat both rear drums ang ireplace ganun din sa kapag harap.

Remember: "all brakes are self-adjusting"

Check the self-adjusting mechanism parang hindi na ata gumagana. Raise both rear wheels at the same time and engage the parking brake. Both wheels should not rotate when forced by the hands.

There are two types of self-adjusting mechanisms:
1. Parking brake adjuster - by frequent usage of the parking brake automatically adjusts the brake clearance

2. Reverse travel adjuster - run it in reverse while engaging the brakes to adjust the brake clearance.

FYI

mayroong adjustment sa brake shoes sa loob ng brake drum. baka sumasayad ang brake shoe sa drum kaya umiinit?

pantay naman ang takbo pag nag brake?

Tol...lahat ba ng brake drum ay auto-adjust? Paano ko malalaman kung anong technique ang gagawin ko para ma-adjust? Hi-ace nga pala O2 ko...Kasi pag nag-aadjust ako ng brakes sa likod eh binabaklas ko pa para i-adjust yung clearance eh...

TIA...

* miked... sir yun nga sabi ng mekaniko, self-adjust daw. Nakita niyang problem ngayon (kdadala ko lang kanina) e hindi daw pantay yung loob ng brake drum after rephasing kaya due for replacement na daw brake drum.

* meledson... sir pantay naman preno. alang kabig.

mga bossing talaga bang kailangan ko na magpalit ng brake drum... sabi mekaniko e hindi na raw advisable ipa rephase ulet at masyado na raw ninipis? up ko lang question ko "magkano kaya ang brake drum (for toyota revo glx) at saan nakakabili besides sa casa?" in case kailangang na talagang magpalit.

Thanks again!

Sir Erick,

i'm no expert on brakes systems ha. Through DIYs lang ako natuto with the help of manuals.

Paano ko malalaman kung anong technique ang gagawin ko para ma-adjust? Hi-ace nga pala O2 ko...Kasi pag nag-aadjust ako ng brakes sa likod eh binabaklas ko pa para i-adjust yung clearance eh...through frequent usage of the parking brake mag-aadjust yung clearance...kung hindi parking brake equipped e malamang reverse travel adjuster yan...run it in reverse then apakan mo lang preno while in reverse

TIA...

1. "Hot" brake drums may be caused by poor quality shoes. Or maybe shoes that are "bonded".
2. Check the brake system again for improper installation. Sometimes, the parking brake is sticking causing heat build-up.
3. Refaced drums done by a qualified machine shop rarely cause a problem. They know the tolerance in which a drum can be machined. They would advise you if it can't be resurfaced anymore.
4. Rear brakes that are not balanced doesn't cause vehicle pull, i'ts the front disc brake.
5. Any reputable auto parts shop sells brake drums and components.

sir ask ko na din, may napansin din po ako sa auto ko na "tog..tog...tog" sounds kapag nag-aapply ako ng brake, after ito na ayusin yung power steering rack ng auto ko due to leak, at palit ng bearing both side ng front wheel, sa ngayon po wala na yung leak ng power steering rack. ano po kaya ito? thanks in advance..........
