Would it be a good idea to remove the abs? I have an air bubble in my brake system and i can't get it out. I tought about removing the abs so there would be no bubble anymore. the engine bay will also look cleaner

what do you guys think? Is it against the law? I suppose but how bad is it?

Is it hard to do?

thanks a lot

Are you sure there is a bubble? Every third gen I have ever been in if you brake, and then pump the brake the pedal gets firmer. I would love to get rid of it, but it is normal.

I imagine the ABS should bleed, just like if you change fluid. Start at the right rear, then left rear, right front, left front.

 

well it started doing this when i changed my brake lines for stainless ones.

the problem is the conception of the system, they put lines higher than the brake fluid tank so the air stays in the line and can't go back in the tank. This is the only car that i have seen who has that problem of conception.

when i bleed the brake, the bubble will only go up and down, up and down, etc.

i should see a difference with my stainless brake line but i only see a difference on the second pedal hit.

Whoops should have got a shop to do it...

 

the problem is that i removed all the calipers to paint them, that was the problem.

i don't think a shop would have done it better than i, brake bleeding isn't a big thing to do.

Do you always take your car to the shop when you want to do something on it? Well i don't since i know they don't know a thing about rx7 and i prefer to learn while working on it and saving big money.

The air must come out if you push the fluid through, like when you actually change brake fluid. Start at the right rear and don't actually bleed, but leave the valve open and keep pumping the pedal until fresh, new fluid is coming out. Do that at each wheel and your set. If there is so much air that you can't get the pedal to push it out, use a pump at the bleeder. I rigged a pump at one time from a gear lube pump that you get to fill your tranny or diff. Just get a big jug of brake fluid and rig some adaptors to get the pump onto the bleeder. Open the bleeder, remove the brake fluid reservoir cap and start pumping. This will force fluid all the way through the system and out the reservoir. Be careful not to let the reservoir overflow. This has worked everytime on every vehicle I have tried.

 

what??? pumping the pedal and letting the valve open? hope this is not what you meant, you are going to suck a lot of air when the pedal is going to come back up...

but that is not the point, is removing the abs a good idea?

Unless the car is strictly a RACE car and will ONLY be driven on the track where you generally know the charteristics of the pavement - NO removing the ABS is NOT a good idea! it is a LIFESAVER in emergency situations especially driving in reduced traction situations like Rainy days.

I sorta have the same problem in my B2200 with the abs. I put the brakes on and they are very sluggish and then when you are aboot to stop, they drop down even further (really annoying!). I thought that there was air in my brake lines but, I just remove the abs fuse and the brake pedal is high and stiff, the way it should be. (it goes back in for winter, so I can actually stop in the snow )
Ive been in situations where I had to stop really fast in my truck (with and without abs activated) and I felt that I had more control without it activated because with the abs on, and you slam on the brakes, the pedal hits the floor and I cant do anything but hope I dont hit the guy infront of me (and it doesnt even rumble or whatever like the abs should). And yes my abs does work properly, I had it checked out by a mechanic that also drives a B2200, so...
Id suggest, one day when its all sunny like, go to a parkin lot or sumfin, take the fuse out and drive around the parkin lot, see what it does. I know the abs on the rx-7s are bester than the ones on my truck but yah know.
Anywhoop, good luck wit your problem

 

Snufelupogus:
If your pedal is going to the floor w/o locking the weels OR getting the pedal pulsation - then you DO HAVE A PROBLEM take it to a different mechanic - test your abs by driving along the sholder of a rural road w one side on pavement and the other on the dirt at about 30 mph then slam the brakes on , you should stop fairly straight w/o locking any wheels and you should feel STRONG pulsations in the brake pedal. - The ABS pump can have air in it and not show any problems on the diagnostic checker.

 

Thanks Maxpesce.
a- The abs is only on the back wheels (dont ask me why, I think its retarded)
b- Im not gonna do that shoulder thing cause theres snow everywhere
c- Ive taken it to aboot 3 different mechanics and they all say that what is happening is normal. The Speedy Muffler guy is the one with the B2200 of his own, he says it happens to him too, and he told me to drive with the fuse out in the summer. The Midas guy said that all B2200 do that, and the only japanese mechanic in town says that there is nothing wrong with it. So go figure.
IMO, all I think the fuse does it f*** with the brake pedal and control the lil light on my dash board.
Ah well.
