Guest chiefvinso Posted June 3, 2008 Share Posted June 3, 2008 OK, I have looked all over the web and in owners clubs but cant find an agreement on how to completely bleed the system. I understand you start with the furthest caliper from the master cylinder and work towards the nearest caliper. My queries are: 1. Does the reservoir cap stay on and only off to refill? 2. Does the car run or switched off? 3. Is the hand brake off or on? 4. Does the peddle need to be pumped or does gravity force it out, albeit slow? 5. How if any does the ABS affect the process? 6. Is it a 2 man process or can it be done well with 1? Sorry for the long list but I installed a big brake kit along with new rear pads and my hand brake travels 3 times the distance which does make sense as the rear pads are alot thicker than the old ones. Any help in clarifying this as I'm going mad! Ta, Keith Quote Link to comment Share on other sites More sharing options...
carl0s Posted June 3, 2008 Share Posted June 3, 2008 I've only done it once. Handbrake should have no effect with the Supra, because the handbrake is a totally separate drum-brake inside the rear disk's bell. I had cap off all the time, engine running from what I remember. I did it how they say - furthest away first or was it nearest first.. whatever it is. I used one of those clip on one-way tubes to bleed it. Gunson brand I think from Halfords. All by myself. I wasn't confident in the technique because the bleed nipple/valve seems a loose fit as though it's going to let air back into the system through the threads, but it seemed to work fine and I did a track day with a hardcore driver driving the car for a few laps. We had smoking pads and blue disks but no pedal problems whatsoever. The only problem was that the fluid level dropped very quickly so I was running back around to the reservoir to refill. Some tight-fitting container would have been nice so I could have kept a load filled up in the container draining into the reservoir automatically as it flowed out the bleed nipple/tube, but instead I had to just keep topping the reservoir up to the top.

JustGav Posted June 3, 2008 Share Posted June 3, 2008 The engine needed to running on a TT VVTi facelift which had ABS in order to prime the ABS system and allow bleeding. Quote Link to comment Share on other sites More sharing options...
Guest chiefvinso Posted June 4, 2008 Share Posted June 4, 2008 Ok, bled the whole system and this is how: I had the car on stands with all 4 wheels off and back on after the Front Right has been completed. The car is then removed from the stands and sits on floor as designers intended. The handbrake was off during the whole process. 1. Start at Left Rear 2. Attach bleed pipe on nipple and slacken 3. Pump brake pedal with hand to point of resistance, then return and repeat. Hold on final push while friend tightens nipple (keep an eye on fluid reservoir and fill accordingly) 4. Repeat steps 2 and 3 on Right Rear 5. Start and let engine run (make sure not in gear), think this helps with ABS? 6. Repeat steps 2 and 3 on Front Left 7. Repeat steps 2 and 3 on Front Right 8. Turn off engine 9. Check fluid levels and adjust accordingly 10. Check nipples 11. With all wheels on and car off stands. Turn ignition on 12. Pump brake pedal until it hardly travels and is solid 13. Check handbrake 14. Slowly test drive I now have a good bite. Remember not to let the reservoir run dry. Hope that helps, if it doesnt make any sense let me know Keith Quote Link to comment Share on other sites More sharing options...
