got flat tire. put 13 yo spare wheel. tire got shreded when driving. damaged brake hose. lost brakes but luckily when i stoped at traffic lights so im alive. (tire got shreded on interstate).
question is can i use valvoline dot3 dot4 syntetic fluid and how many 32oz bottels will i need.
also i ordered brake hose from advance auto is it good? at dealers i have to wait at least few days forhose

 

im glad you are ok. and i hope everyone is as well.

people dont give their spare tires any thought until they need them.
a lot of people dont maintain them. the full size and smaller can lose air pressure,
and once they are installed, no one follows the max speed printed on the tire. as well as
a lot of people dont get their regular tire replaced asap.

anyways, you can use dot 3 or dot 4. or whatever was in there. if it was dot 3 you can use a
dot 4 that is compatible with dot 3 (itll say so on the label.) i think the smaller bottle is somewhere
around 12 oz and that big bottle should be enough for the whole system.

you might need (2) 32 oz bottles to completely fill AND flush out and more importantly BLEED
out all the air from the system. a bottle is probably only $8 or so.

as for the brake hoses supplied at autoparts stores, yeah those are just fine.

 

i had a full size spare that looks like brand new but it was old or had some defect
as for brake fluid im not sure if i can use full synthetic fluid
i know that i cant use dot5 in second gen gs

 

dot 5 is considered over kill for a regular, daily/street driven car. dot 5 is not compatible with anything else, and you would most likely not need the performance of dot 5 on a regular/street car.

dot 5 is silicone based unlike dot 3 and 4, which are glycol based. dot 3 and 4 are compatible with each other whereas dot 5 is not compatible with 3 and 4.

you have to completely flush out your braking system to run dot 5.

but none of that has to do with running synthetic/full syn brake fluid.

ALL brake fluid is synthetic. since polyethylene glycol does not occur in nature = synthetic

here is info straight from lexus:

^that link is from this link: http://drivers.lexus.com/lexusdriver...-manual-search

page 384:
"fluid type: SAE J1703 or FMVSS No. 116 DOT 3"

 

thank you for that info

 

yessir, glad to help
