Help! Naninikit na preno?

[davesabog]

Good evening mga sir. Need your advice and opinions.

Pina-service ko yung brakes ko last week dahil "sumusubsob" at naninikit. Ito yung ginawa: reface rotor (2); reface drum (2); replace brake pads (2); overhaul caliper kit (?).

Malaki improvement ng auto ko kasi hindi na siya "sumusubsob" kapag nagprepreno, kaso naninikit pa rin. Binalik ko kahapon sa talyer, nilagyan nila ng langis yung mga piston. Naging okay na, matagal ko nabyahe ng walang nararamdamang paninikit.

Ginarahe ko yung sasakyan kahapon ng 5pm at kaninang 1pm ko lang ulit ginamit pero wala pang 3 mins eh nanikit na naman yung preno.

Matic yung auto, tinest ko habang nakahinto nilagay ko sa Drive, hindi umaabante yung kotse pero kapag binobomba yung preno umaandar na siya. Tapos preno uli tapos maninikit ulit. Intermittent siya.

Ano po ba sa palagay ninyo ang dapat pa ma-check dito? Nabanggit sakin na baka magpalit daw ako ng hydrovac.

Maraming salamat po.

nilagyan nila ng langis yung mga piston-your automotive brake system is not designed to work with petroleum mixed with your hydraulic system. it will dissolve your rubber components.
if it continues to drag even with the rebuild of the calipers, check your brake hoses, usually, from age and exposure to old contaminated brake fluid, they constrict at the opening and not freely allowing the brake fluid to return to the master cylinder when the brakes are released. if you had the master cylinder overhauled or replaced, check the push rod between the master cylinder and the brake vacuum booster. if the push rod is too long for the "new" master cylinder, it blocks the compensating port of the master cylinder

Thanks for the input sir.

Which rubber components? Should I have the oiling of the pistons reverted? I've just had the car for over a month now, hindi ko pa napa-overhaul yung master.

caliper seals, wheel cylinder rubber piston caps, master cylinder piston seals, residual pressure check valve, proportioning valve and all components having rubber in them. take note: petroleum is lighter than brake fluid, this means even if it were the calipers "lubricated" by einstein, the oil will eventually float and damage the master cylinder. just wish you don't have anti lock brakes, the module is pricey

Whoa! Still not familiar with the car, it's a Civic 2003 LXi. Please tell me it has no ABS.

If you don't see an "ABS" indicator on the intrument panel as you turn on the ignition key, withour starting the engine, then your car is not equipped with "ABS".
which brake is giving you problem? the front or the rear?

No ABS on the instrument panel. Front brakes sir.

Not sure but try replacing the brake fluid. Baka madumi na and build up of small dirt kaya naninikit.

[KIANTOT]

Try mo muna ibleed yung break master at front brakes

[davesabog]

*[archie] Bago yung fluid ko nung nagpa-overhaul ako.
*KIANTOT hindi na siya na-bleed kanina.

Update guys. Medyo okay okay na yung preno ko. Pinapunta ko kanina dito yung mga mekaniko kasi hindi ko maitagpo papunta sa talyer nila. Hindi ko masyado naantabayanan yung kinalikot nila (kasi sa basement naganap ang gawaan). Nakita kong nakabaklas yung master at dun sila may ginagalaw.

Ni-roadtest namin mula dito sa Katipunan hanggang dun sa Motech Cainta, tumatakbo na naman pero may slight drag minsan. Ni-roadtest nung supervisor pero okay na naman daw. Ako uli nagmaneho at okay na naman, pero may nafi-feel pa rin akong drag.

Wala na akong mapigang sagot sa kanila kung ano na gagawin dun sa drag. Naintidihan nung supervisor yung concern ko pero hindi na daw sa preno yun, ang sinuggest sakin magpalit ako ng ATF.

I can say naninibago ako sa takbo ngayon, dahil nung linggo eh mas malakas yung hatak.

Ano sa palagay ninyo mga sir?

[KIANTOT]

Try mo sir mag pa second opinion sa ibang mechanic kung talagang hindi na sa preno yung problema
