Brake line repair

http://i65.tinypic.com/2pr5wy9.jpg
yung sira po sir nasa likod ng wheelcylinder na brake line. di ko napicture-an
ka itsura po ito nung line sa pinag rerefillan ng brake fluid.

may alam po ba kayo nagrerepair ng brake line? kasi noong monday nagpaayos ako ng drumbrake nagka leak sa left side. after ma install yung mga new parts(wheelcylinder at brake shoe) habang i ni air bleed na nung mekaniko yung left drum brake nakitaan ng leak sa fittings from brake line papuntang wheel cylinder, niremedyohan lang ng teflon tape uing thread para di daw mag leak. yung sa right side naman ay ok, ang problem lang ay dun sa left side.

today nag hanap naman ako dito sa amin, may napagtanungan ako if nag rerepair sila ng brake line.
1st shop: sabi ng mekaniko, pag papalitan yung may leak na brake line ang replacement is copper imbes na yung katulad ng original na nasira.
2nd shop:sabi ng mekaniko is puputulin yung nasirang part ng brake line at lalagyan ng o-ring yung fitting papuntang wheel cylinder para hindi mag leak. at nasabi niya ay natutunaw daw ng brake fluid yung teflon.

tama ba copper ang ipalit or may mas maganda pang solusyon? yung sa oring ba ok din? yung tungkol sa teflon natutunaw ba sya ng brake fluid?natakot ako pagkasabi haha kaya hiningi ko nalang contact number nila, magkaiba kasi procedure nila haha.:lasing:

i haven't peeked under the car in a long time, so i don't know if copper tubing or rubber tubing...
what i do remember is, if orig is copper, then replace with copper. if orig is rubber, then replace with rubber.
and once it leaks, replace. teflon just doesn't do it.
good luck.

the fittings probably need more tightening, for hydraulics you need a counter wrench against the tightening wrench.

alam no naman mga kunwari-mekaniko ...

In the u.s. it is against the law to use copper for hydraulic brake lines. If the occupants of the car die in an accidental due to faulty brakes, that idiot of a mechanic can be charged and found guilty of manslaughter.

The brake fittings do not need Teflon tape. The fittings are either 45° flare nuts or ISO bubble fittings. If they don't seal, replacement is necessary.


Look for a competent automotive technician not a plumber.

*dr.d depende ata sa model ng car and sa type ng brake(disc or drum) yung itsura ng lines.example po if titignan mo yung picture sakin, makita mo yung may clamp is rubber brake hose yung before pinagkakabitan is the brake line then brake hose thenbrake line uli po bago mag wheel cylinder.
*stockengine
yes dapat magtanong muna pag parang panget yung procedure nila gumawa iwas muna.
*mina_nuka
oo nga e hirap makahanap ng shop na may nagfflare ng brake line dito sa parañaque.
yung napuntahan ko ay autosupply tapos sa harap may mga mekaniko.>_<

try ko muna dito kung mayroon.
if mayroon kayong alam na nag flare ng brake lines malapit sa paranaque or las pinas, pa share naman po ty.

iniisip ko nga din pala if yung sa mga jeepney kung pareho lang procedure sa paggawa ng brake line.

As per your posted picture, replace the wheel cylinder and/or the brake hose. Usually, the softer aluminum wheel cylinder threads get stripped first before the flare nut fitting.

so where is the leak? if it is at the end of that length of rubber tubing with the vise grip, where it screws into the brake slave cylinder inlet, then just simply replace that hose. dami-daming nabibiling brake hose na yan.
the other possibility is, your slave cylinder is defective, probably at its inlet port. if so, then you have to replace it.

btw. sigurado ba kayong sarado yung bleeder nipple? baka yun ang source of leak?

this is supposed to be a very simple problem. i think the cause of the "complication" is TS's in-ability to show the picture of the actual leak.

good luck, TS.
heh heh.

That should be a simple repair job for a knowledgeable mechanic.

Just replace the rubber brake hose (not copper tubing). If that doesnt help, buy a new brake cylinder.

TBH, yung replacement madali. Hassle jan yung bleeding.
