When replacing the cast iron combination valve, with the brass valve, tell this DIY "Greenhorn" what amount of brake bleeding might be required-and, give the specific steps, in the proceedure? NOTE: My 87' TR, has only a true 8,000 actual miles on it-but, I thought that I might be wise to replace the valve, with the correct brass one-before trouble developes with getting air in the lines! Please try to speak English-instead of in "Greek"(HA! HA!)! Thankyou

I vote for all four wheels since all the lines go through that thing.

Back ones first far side then near side then the front same order.

Just my .02.

Do you bleed these things with the key on and the Powermaster motor running or just do it the old fashion way?

My vote in adition, is to install the check valve type bleeders and open them all with hoses into some containers. I also recommend Castrol Dot4 LMA Brake fluid. Higher boiling point and less affinity to absorb moisture from the air. Also gives a firmer brake pedal. Gene

Someone noted that the instructions on the gnttype.org say with the key on.

The shop manual says to bleed the master cylinder with no power assist which I take to mean, key off. It does not specifically address bleeding wheel cylinders with a PM>

All my cars have been converted to vacuum, but I normally gravity bleed the brakes because it does not introduce air into the system, potentially, when pumping the pedal.

I just open all the bleeders and drip them into a bottle until I have clean fluid and then shut them off.

I have been using the synthetic or maybe, semi-sythentic Valvoline fluid lately. I used to always use the Castrol which is excellent.

Is there any problems associated with or special steps needed to changeover to either Castrol DOT4 LMA Brake Fluid(That ILBCNU6 is using)-or the Valvoline Synthetic-or, Semi-Synthetic brake fluid(That Steve Wood is using)?

STEVE: Is the Valvoline Synthetic or Semi-Synthetic brake fluid Dot3 or Dot4 rated? Mikal
