Proper way to replace Brake Fluid

[RedHorse]

kailangan ba i-bleed sa lahat ng gulong para bago lahat?

Kasi may nakita ako sa isang service shop, na pinalitan lang yong nasa container. Wag lang daw apakan yong brake.

[fierari]

pag palit ko ng fluid binubuksan ko lahat ng preno... bale overhaul.


kalas ko lahat pati yung master :mrgreen:

RedHorse,
Mali iyon. Parang dinrain mo lang yung coolant sa radiator without draining the coolant in the engine block. So maghahalo ang dirty sa clean brake fluid.

[Ungas]

Open all bleeding screws from 4 corners, pump the brakes until no fluids come out. Dismantle master cylinder check all gaskets and clean with plain tap water. Check for any signs of cracks and swelling. Dry all parts and BE SURE THAT IT IS REALLY DRY before putting it back in the master. Close all bleeding screws. Fill in with new brake fluid, release one screw at a time and bleed until the new fluid squirts out. Repeat procedure on all remaining screws. Test drive vehicle and check if further adjustments are needed on the brake drums.

Also, be careful not to spill any brake fluid on your paint job... malakas kumain yan...

...oh man tell me about it! I just had my clutch master overhauled and medyo gifted yung gumawa and some good ole DOT3 dropped on my fender. Buti na lang nakuha pa sa rubbing

if you only replace the fluid bleed one by one. but if complete overhaul better change all rubber cups and o rings.

when i overhaul the brakes i usually dont wet the the used rubber cups, and orings if they were to be returned because i read in one manual that it will expand once it will have contact with water, ok lang if it is new.

use only water and soap to clean the metal parts. dont forget to put rubber grease at the o rings for the pistons in the caliper and rubber cups before reassembly. and use sand paper to remove brake dust on your pads.

so as not to damage your paint, look for a small hose that will fit in your bleeder screw and a container on the other side. dispose of used fluid properly. if you only replace the fluid bleed one by one. but if complete overhaul better change all rubber cups and o rings.

OT: sir ARB whats the brand of this rubber grease? and where can i buy it? aside from the one that comes with the repair kit. Does the rubber grease also prevents the caliper pistons from getting stuck-up by rust? Which it is prone to, especially after frequent wading through floods. Or, its just an assembly lubricant?

Thanks!

Yun red grease na available from any service shop (like caltex, shell) na ginagamit sa mga rubber boots/fittings ng mga suspensions or ball bearings. Castrol is a brand I usually see, also available from complete autosupply stores. (Paki correct na lang kung mali ang pagkakaalam ko)

My 2 cents.

[ARB]

rubber grease is the one that comes with the kit. the ones we use for bearings cannot be they will damage the rubber. some you can find sa hobby shops the grease which tamiya use for the plastic gears.

ordinary red grease lang din kaya itong mga nasa sachet na kasama ng mga brake repair kits? Yung Petron grease ata yung red and scented pa. Hindi ko pa na check yung Castrol baka iba ito sa caltex or shell. Pero dapat ata, yung hindi petroluem base na grease para wag mag swell yung rubber parts ng brakes.

How about the Mobil 1 Synthetic Universal Grease, pwede kaya ito sa mga brake rubber parts?

Pero naka gamit narin ako sa caliper piston rubber seals ng ordinary bearing grease, yung high-temp pa nga. Umubra din naman hindi namaga yung rubber. Kaya lang duda pa rin ako na baka me bad effect sa rubber, unlike the rubber grease that ARB mentioned.

[otomatic]

Thanks ARB! Alam ko yung Tamiya grease for plastics, ok din pala ito sa brake rubber parts. :D

how often do you change your brake fluid?

[OTEP]

It's an annual actity according to the Kia Besta service schedule. Ewan ko lang sa Pajero.

[vinj]

Owners manual calls for a brake fluid change every 40K in some cars... Some naman anytime between 20-40K. It also depends on the type of fluid you use and how often you submerge your car in water...

what do you mean submerge? floodwater wading?
di ba leak-free dapat ang brake fluid lines? how will water get into it?

Bleed the the brakes farthest from the master cylinder first. On RWDs or 4x4 trucks it's: Right Rear, LR, RF, LF. On many FWDs or on vehicles with diagonally split braking systems: Right Rear, Left Front, LR, RF.

Brake fluid flushing can be done using alcohol (100% preferred but 70% Green Cross will do). Crack open all bleeder screws and empty master cylinder. Fill with alcohol... pump until empty... fill with brake fluid... pump till empty... fill with brake fluid again... pump until low but don't empty reservoir... Close wheel bleeder screws... Bleed master cylinder ports (front and rear) by cracking lines open... Bleed individual wheels in proper sequence...

You can also flush by simply using new brake fluid. Pump out old brake fluid, as above, and keep on replenishing reservoir until "clear".

For vehicles with ABS, check factory service manual. Fully pressurized ABS accumulators at 2500psi if opened without relieving pressure will cause serious injury. However, in most cases, individual wheel bleeding procedures are the same.

[RedHorse]

Thank you for your replies. (wala bang applause na emoticon)

May ABS pala yong trooper.

CASA na naman ako at CASH na naman ito grrrrrr.

[Engr]
