Brake Master leak

[benchph1]

Baka replacement lang yang adler. I know “nissin” ang OEM brake parts ng Honda.

Same din kaya ito ng principle ng dialysis for ATF?

Mekaniko ba talaga napupuntahan mo? Hindi sila marunong mag bleed ng brake line?

Bomba-pirmi lang yan. A simple but 2-man job.

We bought a brake vacuum machine a few years back for the diy job. Wala kasi ako kasama to do the bomba-pirmi

Na confirmed mo each of them do bench bleeding? That's great! I'll call each of them on Monday. Thanks.

I think bleeding brake fluid is rocket science.. consisting of tubes, valves, critical liquid and mixing which all rockets do..

[StockEngine]

no bro, ask them if or maybe they do proper bleeding and bm replacement

Car zone said they don't individually bench bleed but do it when installed by tapping the brakes.

I want to know the technicalities.. Supposed you installed it empty and add brake fluid to the reservoir with air in the cylinders.. and you repeatedly press the brakes with the bleed valves in the brake calipers open (lahat ba na car meron bleed valve?).. can all the air be sucked out eventually or 100% required talaga ang bench bleed??

Lahat meron bleeder valve.. lagyan mo lang ng brake fluid pag nag start na tumulo.kabit mo na brake lines tapos bleed all 4 brakes starting from the farthest wheel

the air isn't sucked out in the traditional manual method.
the air is gradually pushed into and thru the brake lines, exiting out via the bleeder nipples, by the traditional "tapak.. bitaw.." process that every other tsikoteer worth his rear view mirror, has experienced.

brake bleeder nipple is opened, and mechanic shouts "tapak". the assistant (you! heh heh.) step on and floor the brake pedal, and the fluid from the brake master cylinder is pushed into the brake line. whatever air is in front of it, is pushed into the line.
"bitaw". the brake master cylinder spring pushes the piston back, allowing fluid from the reservoir above to fill up the cylinder.
"tapak". this new fluid is pushed into the brake line, further pushing the air downward.
the process goes on and on, until the mechanic sees that no more air, but brake fluid, exits from the bleeder nipple.
then he goes on to the next wheel and starts all over again, until all four wheels' brake slave cylinders are bled.
all thruout, someone keeps an eye on the reservoir, making sure it is topped up when the level gets low. if it gets too low and is emptied, air is re-introduced into the system, and the entire process must be repeated.

the entire process can be fast. 15-30 minutes.

filling the master with fluid on the bench, or when already bolted in place? it's a matter of choice, in my opinion.
but... if it is already full of fluid and some spill out onto the paintjob while bolting it in place...


btw,
you should do something about that ruined paint on your brake booster. baka kalawangin at ma-butas.

Before the assistant bitaw the pedal.. dapat I-close yun bleed valve right? So it won't suck in the liquid it releases to the bottle? Kasi I'm reading some where they need to close the valve before releasing the brake.. pero parang some don't...

Here it needs to be closed:
How does a brake bleeder screw work?

"The bleeding process basically involves applying brake pressure, slightly loosening the screw - about 1/4 of a turn - to raise the end of the screw and allow air and fluid to flow into the hole at the bottom, through the screw and out the hole at the top. The screw is then tightened again and the brake lever released, drawing in more fluid from the reservoir and the process repeated until there is no more air left in the system. "

About Bench Bleed.. it is really very important:

see is bench bleeding necessary? - Honda-Tech - Honda Forum Discussion

"you don't have to bench bleed, but but there's alot of air which gets trapped in the MC if you don't bench bleed it 1st; plus you'll go through 2-3 bottles of brake fluid if you don't bench bleed it (without bench bleeding it will seem like no matter how much you bleed all 4 corners, they'll def be air with bubbles in your brake system & seem like it'll never **** pure fluid into the bottle). "


Tomorrow to whatever service center I visit. I want to make sure they did bench bleed and close the valve before every pedal release.. but is there variation where it doesn't need to be released?

I just had so bad experience the other day with service center where all the mechanic don't know how to flush steering fluid. He never did it since 2011.. doesn't know how daw.. and he is training about 5 apprentices in his shop.. wanna make sure I won't encounter one like him again...

[k_leos]

I called up different service centers kanina.. some use hose in the bleed valve/nipple.. while some don't use any hose and bottles (for example Car Zone)...

Tanong.. if walang hose and bottles and gusto ko matanggal old black brake fluid.. paano matanggal? ipa drop lang yun old fluid sa floor from bleed/valve/nipple? Won't it hit any metal parts and cause corrosive reaction?

Also the technique where one opens and closes the valve for every pedal press is called 2 man method.. the one where you don't open and close the valve is called one man method.. ano mas effective.. ano usually ginagawa nyo?

I want to see to it tama gawin bukas.. kasi in the case of my steering fluid replacement at the corner of 14th st and Gilmore the other day.. hindi magalaw steering wheel for 10 minutes.. nagulat nga yun mechanico sabi nya baka sira na pump.. at nagulat rin ako kasi cost ng pump ay 30k.. pero after 25 minutes gumalaw naman steering wheel after he tried all sorts of combination... want to make sure hindi ulit mangyari bukas.

Salamat sa mga advices nyo.

brake still not fixed hahaha

my two cents. enroll in TESDA and fix your vehicle DIY.

I called up PowerTor. Talked to the technician and discussed with him how he would do it. So far, ok naman kasi they are willing to spend 2 hours to bleed using hose and bottles whereas in Car Zone in banawe.. they don't have time to use hose because sobra daw haba pila ng mga cars pagawa dun so hindi ma focus on detailed bleeding.

When I passed by Honda to buy brake fluid on way to PowerTor. Kinausap ko yun service adviser asking him on the minute details of the process. So far marunong naman mag bleed. And considering meron about 100 mechanico sa Honda.. then pinagawa ko na lang replacement sa Honda casa with 3,000 pesos surcharge for parts bought outside. Malayo rin PowerTor and my brakes may not last that long. At least I can complain to Honda management if hindi marunong mag bleed and make sure tama yun pedal play (which dr. d emphasized pero hindi ako familiar if not normal ang pedal play)

About yun service center who doesn't know how to flush steering fluid and doesn't focus on bleeding.. remember the mechanico there introduced air to my steering system by opening the drain at the pressure hose side and partially pa.. at least hindi nasira yun pump or rack and pinion.. kasi air in steering fluid can damage the pump. Since mukhang ok naman yun pump.. then I can forgive them for their mistake. I already removed the pictures of their shop at imageshack.. the photos in this thread will disappear in a while too.. if not.. then let's request the mods to just delete it (only me and dr. d posted the pics (when he replied)). It is only for reference for those immediately people here at present for our discussion and not for future reference for hundreds and thousands who are not present with us now. It is because of them that I realized some mechanico doesn't focus on hydraulics physics or principles (which is what the steering system and brake system rely on pa).

Thanks for all who help as it gives me the knowledge and make me understand the process a bit more giving me the information I needed to decide where to have it replaced with peace of mind for years to come...

my goodness... sa dami ng pinuntahan nya. ang laki na ng ginastos sa gas at ORAS... pinagawa nalang sana sa CASA para natapos na...

[k_leos]

I called up one of the shops recommended by Stockengine.. so far they have hose and bottles naman for the bleed nipple/valve.. problem is.. they don't have any hose for bench bleeding the master cylinder.. saan ba maka bili nito locally?



sino sa inyo mai extra ganyan?? I need them to bench bleed my brake master.

In case wala ako mahanap.. how do you bench bleed your brake master without using any hose to feedback on the reservoir.. please share your method that can successfully remove all air in the cylinder before you connect it to the car.. thanks!

[sirkosero]

Ang mali ni TS dito, wala sya alam sa preno pero ang dating nagmamarunong sa mekaniko.

Napansin ko lang ha... No issue to pay 12-15k sa casa kahit mahal pero namamahalan sya sa 6500 part +30% handling fee ng casa kung sa kanila ipainstall. Ano nga ba total ng 6500 + 30%? Abot ba ng higit 15k para mamahalan? Labo lang.

Lost in translation kayo dyan. Sa mekaniko, di nila alam na yng bleeding na ginagawa nila sa master is yung bench bleeding na tinutukoy mo. Parepareho sa kanila yan.

After mo pa din namam ipagawa ang brake master mo, ibebleed pa din nila dapat all 4 corners ng sasakyan hanggang maging firm ang pedal.

Isa pang paraan para magpalit ng brake fluid/power steering fluid eh “syringe” method. Higupin ung fluid hanggang sa maubos, tapos top-up lang ng bago. Syempre may bleeding pa din yan.
