Mas madiin ang apak sa preno.

[desert fox]

DI na sya nagbabawas ng fluid.
Funny thing is pag binigla ko ung preno at 10 kmh, para syang dumudulas bago sha huminto pero walang iyak gulong or guhit ng gulong sa daan.

hangin ang singaw...sa hydrovac nga....

[benchman]

ayun sir reym, dalawa na ang nag-agree.... it's your hydrovac, wala ng duda.

[desert fox]

para ding utot natin, kapag ayaw lumabas, kabag...so di tayo makapagperform mabuti anuman ginagawa natin...

kapag nauutot ganun din...pipigilin.....

jk.

[benchman]

bingo! hehehe!

[reym]

meron ba nabibili bago brake booster lang?

[benchman]

parang assembly ang mga bagong nabibiling bago sir e... di ko sure
pwede na po siguro ang surplus, isama mo na lang yung mekaniko para mapili nyo yung good na pyesa. imho lang

[reym]

Mukhang tama nga kay mga sir, nasubukan ko isang beses di noble ko apak tumigas ung preno na napakatigas. Hahanap ako ng booster next week. TY.

Types of Brake Noise
1. Squeak noise when brakes are cold
- usually occuris during 1st few stops
- this is a normal condition and no service action required

2. Squeak noise with brakes at normal operating temps
- semi-metallic pads are noisy compared to OE or ceramics

3. Loud continuous squeak/squeal noise
- occurs with or without braking
- normal brake function when brake pad wear indicators contact the rotor.
indicates brake pads are worn out and need to be replaced
- foreign materials could be trapped in between pad and rotor

4. Groan noise when slightly releasing the brakes after coming to a stop
- sometimes called "creep groan". this is normal and no service action required

5. Groan noise during stopping
- usually caused by glazing of rotor surface as a result of frequent heavy braking
- replace brake pads, then resurface rotors and finish with sand paper

6. Single clunk noise from front suspension when applying the brakes
- can be duplicated by lightly touching the brake pedal
- if brake pedal is pushed hard, the noise is less likely to occur
- the noise is a result of the brake pads shifting in the direction of rotor rotation when brakes are applied
- install appropriate shims and brake grease to pad's steel sliding surfaces

7. Multiple clunk noise
- ABS self-check. vehicle's ABS systems performs a self check when the brakes are applied after initial start-up. this is normal and no service action is required

8. Rear brake squeal
- due to accumulation of brake dust and dirt in between pad/shoes and rotors/drums. clean and lubrication is required

Brake Judder
- caused by rotor thickness variation (RTV) when the inner and outer surface of the rotor are not flat and parallel, the brake pads will follow the low and high spots on rotor during braking causing the brake piston to "knock-back" causing pulsation in the pedal

RTV causes:
1. Rotor run out - if the rotor is not true (perpendicular) to the hub center
2. Vehicle storage - area not covered by pads will rust affecting the friction characteristics between rusted and un-rusted areas
3. Lug nut overtorque - if lug nuts (studs) are overtightened usually with an impact wrench


Hope this helps. i'm sure there are other tsikoteers here with the same problems as yours.
Guys, just add some info. i'm sure my "brake bible" is not that complete.

check mo nuna booster before mo palitan.engine off tapakan mo brake pedal hanggang tumigas, hold mo tapak sa brake while starting the engine, pag bumaba ng konti ang pedal that means ok pa ang booster.

yung stopping power depende sa quality ng pads, yung mga composition brake mahina talaga kumagat lalo na pag mainit na. try mo din ibleed amg system or better i flush mo and replace with new fluid. check mo din adjustment ng rear brake shoes.

Bumababa naman sya pag start ng engine kaso minsan mas madiin apak ko para huminto tapos kanina malapit ako sa hump i pressed the brake one time, bumagal ung sasakyan at normal ung apak ko (2 seconda ang difference sa una) sa brake ung pangalawang apak ko eh mataas at napakatigas ng brake. (ung parang di umaandar ang makina ang height at tigas).
