    My next task on the Testarossa is to flush the brake calipers and the clutch. Been doing my home work on the how-to and buying necessary tools needed to help me do this correctly and efficiently. I will be following the steps by TDC again on this (http://truedriverscar.com/docs/testarossa_brakeFluidFlush). The car has ATE blue in it right now, so I do plan on going to either clear or amber to help me better ID the flushing progress since I am a rookie at this. With that said, I have two questions that come to mind immediately about this, so like always, any help will be greatly appreciated.

    1) With the clutch bleeder valve hiding underneath the heat shield of air intake and filter, I am having a hard time seeing and reaching it. Do you need to remove the intake or is there a trick to getting this done?

    2) Caliper procedure. I have been taught to bleed the caliper furthest away from the reservoir first (RR, LR, RF & LF), but as I understand it, the factory manual has the sequence that is new to me, RF, LF, RR then LR. Not trying to be smarter than Ferrari engineers but can someone explain to me the reasons behind this process and which one do you follow?

    Again, many thanks to all of you.

    as long as there is old brake fluid in it does not matter where you start first. only have to bleed as long until new brake fluid comes out without airbubbles
    sorry, can not explain the procedure F says. italian logic? ;)

    Stupid f/u Q: Do you or can you please give a more detailed step by step instruction on how to do that so I can follow and not make any mistakes? Does this whole thing need to come off or just part of it? Sorry for being such an idiot about this.

    I take off the four nuts (A), then the two nuts (B), then loosen two nuts (C), then loosen clamps at (D), then loosen clamp at hose (E). then the whole assembly slides out of the rubber air elbows and off the plate (5). I then remove the plate because it wiggles easily and you'll lose those washers on the floor if it detaches.

    Take a turkey baster or some device to suck the fluid out of the M/Cyl. reservoir before you start the bleed. Refill with new fluid, that way you don't have to bleed as much!

    Thank you for your response. I do plan on extracting as much existing fluid out of the reservoir as possible first and will refill it with fresh fluid. I also purchased a Motive pressure bleeder and will be using it to complete the job. I was having trouble visualizing how to access the clutch bleeder valve before, and thanks to Veedub00, I am that much more confident about the whole process.

    Removing the 4 nuts, loosening the loop clamp 9, and removing part 7 will allow you to remove washers 6 and wiggle out the shield 5 -- should give you plenty of access to the clutch bleed screw -- JMO.

    Just changed the failed clutch hose on my 86TR and bled the system using Motive bleeder. IMHO, there is certainly no need to do any disassembly of the intake or heat shield. Yes the heat shield is visually in the way, but a good covering on the fender and a bright light will give you a better look without disassembly. EDoug

    Thank you, I will see which method I am most comfortable with.
