SOURCE: 1999 Chevy Tahoe- Soft Brake Pedal

Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

SOURCE: i have a 2000 chevy blazer. had to short fix left

do not drive the vehicle. remove the hoze. replace it with steel line. rubber hoses are not meant for the high pressures of brake lines. it is expanding when you press the brake pedal. very unsafe.

Brake pedal goes to the floor only when engine is running. Pedal is perfect with engine off.


your power brake booster is blown out
the seal has a leak in it
run the truck for 3 minutes and shut it off. with the windows up listen carefully while you gently apply the brakes
listen for a hissing sound of air leaking.
the sound of these leaking is a very soft sound

There may be air in the lines. Bleed all your brakes starting at the farthest wheel from the resevoir, and finishing at the closest one. Try the pedal after its bled. If the pedal still feels soft or travels to the floor there may be a pinhole leak that may be spraying on the underbody of the car, or the seals in the master cylinder are gone filling the vacuum booster(if equipped). Air compresses more than oil so if bleeding works that may be the problem.

Left exhaust manifold continues to warp and leak


Brake Pedal not firm enough.

1. I suspect deteriorated brake fluid, some air in the brake lines and tired flexible brake hoses which are past their useful life.

If the brake fluid has not been changed in the past 12 months then have the brakes bled and new DOT 4 spec brake fluid replaced in the system. (Brake fluid must be bled out and changed at least every 2 years). At the same time look for signs of any minor brake fluid leaks or fluid weeping.

2. In a vehicle of that age I would also be replacing all flexible brake hoses before bleeding the brake system again. These flexible hoses deteriorate badly with age and will swell significantly when you apply pressure to them contributing to a soft pedal feel. This is not expensive to have done and, given the safety importance of the braking system, it is imperative to keep the brakes in decent working condition. Ensure you only use very good quality brake hoses.
Once the brake hoses are fitted, the brake system is bled and the new brake fluid is added into it at the same time.

With everything tight, new hoses and new fluid in the system you should have a solid pedal assuming everything else is ok.
(I doubt that the ABS sensors on your vehicle have anything at all to do with the soft pedal you are concerned about but we cannot test this. It is much more likely that the issue is more fundamental as explained above.
On this site we frequently do not have enough information about a vehicle to offer as much information and comment as we would like).

I hope this helps.

Cheers
Sean

Mushy powerless brakes . changed pads,rotors,powersteering pump.


Mushy brakes are almost always 1 of 2 things:
  1. Air in the brake line; when brakes where changed they weren't bled; this would cause a soft brake pedal.
  2. Most common reason for a soft pedal is a bad master cylinder. Once they become faulty they fail to provide the pressure required to adequately stop the vehicle.
Either way, have this checked out at a brake shop immediately. A soft brake pedal is not something to be fooled with.

04 free star soft pedal has new master cylinder pads and rotors


the master cyl must be filled and bled before install.after installing new bled master cyl,bleed all calipers.once you are sure there is no air left in system then you will need a scan tool to perform a abs service bleed.if you do perform the abs service bleed with a scan tool the brake pedal will be soft and start to fade.
