please help , brake problems

[Adi Agaj]

ok guys,
today i had my rear brakes done on my 92 SHO. I put new pads and new calipers both rear sides (no need replacing the rotors, because they were fine) The front brakes replaced 2 months ago all new pads and rotors. well so i bleded them when the job was done today. The pedal felt looser and softer then before even after bleeding them. I took the car for a ride after i finished and when i braked hard i do not feel my pedal ticking like it use to do when the abs locked all wheels up. After then i went in around all four wheels and when i touched the rotors only front left, front right, and rear right where very hot because of braking and the rear left one not even 20% of the others. I don't think is the caliper because i just put em on today brand new out of the box.

The car skided with one ( more was the drivers side wheel )or both wheels on wet roads when i intentionaly locked up the breaks. however it doesn't seem to skid with the back. Is this normal or is it an indication that the back breaks having trouble now? Also the pedal feels a bit lower. What about if there is any way how to run self test in the ABS control like there is when you do to get the codes from EEC ( electronic engine control) when your check engine light comes on ??. Anyone know where to take it from here? please any advice will be really apprecietd.
thanks

adi

There is a certain procedure on how to bleed ABS brakes. I do not know what it is, but a search will help you find it.
It sounds like you have air in the system still.

Find the procedure, re-bleed the brakes, and you should be good to go.

 

[stevetatro]

The ABS system is split, the right front is coupled with the left rear and the left front with the right rear.

Theoretically you want to do these "couples" together, so RR-LF and then LR-RF.

I doubt a change in the bleeding order would cause the problems you describe.

Is there any chance you goofed when bleeding and allowed the fluid level in the reservoir to get too low?

For the heck of it, some say you can get excess air out of the top half of the brake system by locking up the brakes multiple times on a gravel road.

Good luck.

When replacing the pads, you should always do the rotors at the same time. The brakes won't stop as good otherwise.

Sounds like they need to be bled better.

Adi,

A spongy or soft pedal indicated air in the lines. If one caliper is not getting fluid pressure (cold disk) you may have a rubber brake hose that is deteriorated and swollen on the inside.

IF the ABS needs to be bled it takes special equiptment to access the ABS computer and put the ABS pistons in the position for bleeding.

Very few independent garages have the equiptment, so a dealer is the best bet for the service (IF NECESSARY).

The prior post is correct in that the proper bleeding sequence is right rear, left front, left rear, right front. rangerj

Adi, No, I do not know how to do the valve adjustment. You can check with Fred Hurder Jr(YamahaV6) on the forum. He runs a SHO business at night and weekends out in Spencer, MA.

There was also another guy, SHOOoooo(or something like that) that does some work on the side. IIRC, he is from the Boston area also.

Get in touch with these guys and I'm sure they can help you out.
