#1950 of 2228 Brake problem by song77 Jul 27, 2006 (3:16 am)
I have a 1995 Pontiac Bonneville and the brakes are not working correctly. When I apply the brakes, the pedal depresses about half way and gets hard. The car will brake but not 100%. It seems as though not all wheel are braking. there are no leaks visible and the brake fluid level is full. Any suggestions anyone? Thanks Replies to this message: stewc (Jul 27, 2006 10:36 pm)

Replying to: song77 (Jul 27, 2006 3:16 am) Have you recently replaced your calipers? If you, you may try bleeding your brakes. Even if you haven't replaced either, you should bleed your brakes. The pedal goes down halfway without pressure because there may be air in the brakelines, and it has to push the air out, before it hits the fluid.

Can anyone tell me the correct high and low side pressures for a/c system and equalized pressure at 95 degrees ambient before system is started. I have a 92 Bonneville thats been converted from R-12 to 134A refrigerant.

Replying to: richard47 (Jul 31, 2006 12:57 pm) I assume you have automatic temperature control rather than manual controls.   It may be you've lost vacuum to the inside of the car from the motor. See if you can find the little black tube from the intake manifold running upto the firewall to a small plastic vacuum tank or running under the right front fender. See if you have vacuum there. When there's no vacuum controlling the doors in the heater box, defrost is where the air comes out for safety reasons to keep the windshield cleared.   You may have had a problem with the programmer box which interprets the sensors and input settings. There are various kinds of failures that happened with little vacuum connectors and electric motors that don't have the flashing indicators. Up till 1994, if you pushed on two buttons on the settings, it would read out a number telling what it senses is wrong. But I believe in 1995 you have to have a Tech II to see what it's complaining about.   Check for vacuum.
#1956 of 2228 92 Bonnie A/C leak by norm45 Aug 02, 2006 (5:07 pm)
I have a 1992 Bonnie that has a small freon leak at the low pressure valve. Is there a way to replace that valve? The valve that looks like a tire valve. I tried to tighten it, but stll bubbles when you spray water on it. Also is there anywhere you can buy this valve? Or is this a job for a repair shop? Thanks.
