Talking Brakes

Hey,

LURKER NO MORE! Finally a broad band internet connection at the house!

Okay. Nuff said.

Braking systems. I like to race autocross and track days and I think I am going do a lot of that this coming year. My track day in Vegas was cut short by a soft pedal (No how soft was it jokes) and I am not going to let that happen again. I have new steel lines to be put in and I am ready for the fluid. Im thinking Castrol SRF or Motul600 as I am hard on brakes (hold those jokes). The flushing of the system before I put this fluid in concerns me. I have "goo" for fluid now and I will have to get it out of the ABS system. Remind me of the proceedures please.

Flush the brakes per the Service Manual. On 92-up, don't forget about the ABS prime pipe and, if you have a T1 or a Mastertech, you can use it to operated the solenoids.

Use Motul 600 but also, C4 front brakes like cooling air so build yourself some cooling ducts and finally, many people who do track day events and experience brake problems sometimes find the problems are not hardware related but are human related. That is, *how* you use your brakes is a big influence on how they stand to heat.

Thanks Hib,
We met at the Gathering West and enjoyed the tech sessions. I was pounding the brakes really hard and late . The fluid was contaminated and was really softening up after about 10 minutes of track time. The instructors were really impressed with my capability and gave the nod for me to go solo, but the brake fluids just where not ready for any more abuse. Plus we don't trailer our cars do we! I don't use the brakes in the corner at all, only prior to entry and may be a smidge of trail braking if my entry is too fast. I use the throttle to assist in turning the car and get to the point of a 4 wheel drift. then soft shoe (throttle) the exits to minimize rear wheel spin. The auto cross really is my problem. The point and shoot is fun but I have to control mistake correction. The Zr1 really can cook the rears if I don't pay attention to the exits. And when I am in correction mode anger can make me forget that soft foot.

Since its a 91 I don't remember if I need to pulse the abs to get it flushed. I will have to read the manual.

BTW what was the software scan product? easy something?

For a 91, there are two that work.

If you have an old PC with a parallel port and all you want is engine diagnostics, good old Diacom still works well.

If you want to be able to look at ABS codes as well as the engine controls, you need EASE Diagnostics.
