Graham S Posted December 7, 2010 Share Posted December 7, 2010 Start the car up dude and do it with the engine running Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted December 7, 2010 Author Share Posted December 7, 2010 ok ill try that thanks for the quick reply bud! just so i know why do you need the engine running? cheers Quote Link to comment Share on other sites More sharing options...
Graham S Posted December 7, 2010 Share Posted December 7, 2010 I'm assuming your starting from the furthest away from the servo/master cylinder? As in Passenger Rear (N/S/R) Drivers Rear (O/S/R) Pasenger Front (N/S/F) Drivers Front (O/S/F) Hope that helps.. Quote Link to comment Share on other sites More sharing options...

Parry_10 Posted December 7, 2010 Author Share Posted December 7, 2010 ok will try that and yes im doing it in that order and the car is up on stands cheers Quote Link to comment Share on other sites More sharing options...
dude Posted December 7, 2010 Share Posted December 7, 2010 Car running or not you should still get fluid, are the calipers new or used, if they are used check that the bleed nipple is not blocked, the pedal will still depress because of air in the system but nothing will come out, take the nipple right out and check its clear.

Parry_10 Posted December 7, 2010 Author Share Posted December 7, 2010 ok could well be that as well thanks for your input Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted December 7, 2010 Share Posted December 7, 2010 And the engine running helps because it provides vacuum assistance to the m/c Quote Link to comment Share on other sites More sharing options...

monsween Posted January 12, 2011 Share Posted January 12, 2011 Why is this? Because you work with the line that is farthest away from the reservoir first. This means you can fill the line up all the way to the bottom first and get the air out Quote Link to comment Share on other sites More sharing options...
supra steveo Posted January 12, 2011 Share Posted January 12, 2011 how would i go about doing a full fluid change to the 5.1 stuff ? do i need to totally drain the oil first ? Quote Link to comment Share on other sites More sharing options...

I'm not doubting you, I just don't understand how it all works. I like to understand things fully, rather than just know that something's right 'because it is' Quote Link to comment Share on other sites More sharing options...
Terminator Posted January 12, 2011 Share Posted January 12, 2011 Can't remember the exact reasons and it's the only car i've found that it needs to be running but it just does! Changed the brake fluid on mine 8 times, not once with the engine running. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 12, 2011 Share Posted January 12, 2011 how would i go about doing a full fluid change to the 5.1 stuff ? do i need to totally drain the oil first ? You use the new fluid to push out the old, bleed one the brakes to get the level in the master cylinder down to the min level then just top up with the new fluid and bleed through as normal. It should be obvious when the new fluid gets through the caliper, if its really old fluid in the system as mine was it'll be a differant colour, when you have the new fluid through each caliper, bleed them a bit more and job done.

I want to do this too... how much fluid am I likely to need to do the whole system? Does the ABS use the same fluid? Quote Link to comment Share on other sites More sharing options...
nevins Posted January 12, 2011 Share Posted January 12, 2011 Now I have always done breaks the following way PR > DF DR > PF For the reason that these are the callipers linked in the breaking system. Never had a problem bleeding the system this way, and always works first time. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 12, 2011 Share Posted January 12, 2011 (edited) I want to do this too... how much fluid am I likely to need to do the whole system? Does the ABS use the same fluid? The abs is all part of the same system look on here under Braking system http://www.turbosupras.com/pages/en/pages/technical/a80tsrm.htm Motul RBF600 is a good fluid to use, not sure on quantity though Edited January 12, 2011 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Terminator Posted January 12, 2011 Share Posted January 12, 2011 (edited) I think 1.5L will flush out the system. Edited January 12, 2011 by Terminator (see edit history) Quote Link to comment Share on other sites More sharing options...
Parry_10 Posted January 12, 2011 Author Share Posted January 12, 2011 I changed to uk brakes and braided lines wasnt getting anything when i tried to bleed them then tried with engine running and they bled fine Quote Link to comment Share on other sites More sharing options...
Terminator Posted January 12, 2011 Share Posted January 12, 2011 I changed to uk brakes and braided lines wasnt getting anything when i tried to bleed them then tried with engine running and they bled fine I am not suggesting it does not help by running the engine. However, as Toyota, don't mention it in their service manual, I would be concerned that the fluid did not flow through the system without the assistance of the brake servo.

Need4Speed Posted January 12, 2011 Share Posted January 12, 2011 Are you just pumping the pedal with the bleed nipple open? Shutting it on the up-stroke of the pedal will always get the fluid moving. And you don't need the engine running. You should be able to fill a completely empty system with 1 litre but it's best to have 1.5 to be sure you don't get stuck with too little.

nevins Posted January 12, 2011 Share Posted January 12, 2011 Shut it on the upstroke and it won't do a thing. You need to pump it through a few times then when the peddle is down close the nipple. Pump the peddle to see if its getting some force, then repeat. Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted January 12, 2011 Share Posted January 12, 2011 Sorry, I meant shut it before the up-stroke. ie when the pedal is on the floor. Quote Link to comment Share on other sites More sharing options...
