Hey everyone,
I am having problems with my brakes on my 88 vert NA.
Here are my symptoms.
1)The STOP light does not come on when I hit the brake
2a)I hit the brakes, they are firm for the first second then they just sink all the way down to the floor.
2b)When it is all the way at the floor i can still "stop"

These both started at the same time Saturday i think as far as i'm aware.

From what I've gathered problem 2 is either a failing master or failing brake booster line. any help on this? Is problem 2 causing problem 1?

 

Most likely a failing master cylinder. There is a procedure in the FSM to test the booster. Its highly unlikely it failed, I've never seen a bad one.

 

Alright ill look for that procedure. Any other insight would be nice also =)

 

is the "stop" light you're referring to the brake lights? +1 on the master cylinder for the other stuff tho

 

+1 master cylinder

two separate problems though. you need to check your brake light switch on the pedal. use a DMM and do a continuity test on it. make sure that works and make sure the pedal trips it.

 

Alright, im going down to autozone right now to see what they have inline of MC's and ill do the test.

 

well, bleed your brake system first. Maybe you have air in your lines. It will be a cheap way to see if it fixes the problem. If it persists then you can move on to buying Master and slave cylinders.

Check www.nopi.com to see if they have good deals on these parts.

 

I bleed them before, Im looking at them and some of them say Without ABS; Without Auto Adjusting Suspension
How do i tell is my car has these, i think it has the ABS but im not sure what the AAS is.

edit:before as last saturday.

 

if it's a GXL the you have the AAS (Auto Adjusting Suspension) otherwise you don't.

 

its an 88 vert, so I wouldent have the AAS just the ABS.
