Do proportioning valves tend to go out on these cars? Is there a test for those valves? After removing the caliper I moved the emergeny brake arm on the old caliper and brake fluid squirted out. Why would the action of the emergengy brake have ANY effect on the hydraulic system? Thank you, abcus

I tried to follow a few threads,buy still have questions. I have a front passenger side brake that locks up. The car is a 89 gl wagon 4wd.standard trans. I installed a new mc and bench bled it beforehand, I installed a new hose to the caliper, a new caliper and pretty much the brake fluid is new altho I did not flush it. The rotor does not have excess play in it 6 to 12 and 9 to 3 o'clock. The hill holder cable is disconnected from the clutch fork. When cool,the driver's wheel turns more freely than the passenger's wheel. The emergengy brake does not seem to cause any wheel to lock up when applied and released.

Dear Folks, I have a 89 g10 wagon. I tried to look up some threads but no luck. I am replacing the master cylinder and keeping the plastic reservoir. I unscrewed the phillips keeper screw at the base of the reservoir. Can I pry the reservoir off without mashing my seals? Any help would be appreciated. Thanks,abcus.

Thanks for the help. I have reason to believe this car was built in Indiana. It has 270,000 miles on it, and they want 800 dollars for it. It seems to have more power than my 87 gl I am now driving with 200,000 miles on it.

Thanks for the info. The radiator coolant was low that may be a red flag. I have not paid for it yet. Thanks miles fox. Abcus

I am thinking of buying a touring 1989 gl wagon. I checked the thread on vin' s. I do not seem to be able to check it on auto check on the internet, it comes back ,invalid vin. The vin is JF2AK53B1KE002534 Does AK stand for touring wagon? Thanks for any ideas.

Thanks for the help. I checked a few things but forgot to check the bushing above the differential. I raised the rear end up and let the wheels hang down. i tried to move the drive shaft up and down. It moved slightly, but there is rubber involved in the central carrier. It was not loose. should I be able to move it up and down at all ? Drive shaft turns smoothly when I rotate it. I can rotate it 1/4 inch before the wheels start turning. When I am at each rear wheel, and I change direction of rotation quickly, I hear a faint click noise. I did the spring vibration test again but did not feel anything this time. If I switch the brake drums, and if the noise does not follow the drum can i "assume" it is the bearing? I know i still have to check out the diff. bushing.

thanks for the help all. I changed the gear oil in my differential. It was dark but I could see through it and I found no filings with a magnet. The noises are still there. I guess the bearings are next.

I have read a few threads under bearings and differentials but I still have questions. the car: I bought a 1987 gl wagon a year ago. It has 190,000 on it now. I had a new cv joint put on the right front wheel and i installed a new rotor also. It is 4 wheel drive. Symptoms: I have a rasping noise that gets louder when I turn right. When I turn left it goes away unless I only go 2 miles an hour. I took a length of garden hose and put one end above the differential inboard . I heard no noise. Then I hung it out each window near the axle. The left rear axle seemed the loudest. When I backup there is no noise. When I run it on gravel in 4 wheel drive going forward there is no noise. When I jacked it up and held the coil spring I felt vibration when I spun the wheel. That brake drum had a lot of black dust in it. The differential was hot after a 60 mile trip. The driveshaft has 1/4 " play in it. The front and rear bearings do not get hot. The noise stays the same in or out of gear w/ clutch in or out. Noise changes a little with application of foot brake. Hand brake does not change the noise. Questions: 1. Should I change the dif. oil ? 2. Can I use a differential from a 87' gl automatic on my car ? 3. Are there any other ways to isolate the problem ?

Dear folks, I have been out of the loop for awile. I will be at Troutdale Chevon at 10 am if anyone is caravaning to w Wcss. I will wait 15 minutes then be on my way. My cell phone is 415 290-8793 Take care, Bob

Dear Folks, I have been out of loop for awhile, but I drove up from SaN Francisco and I am in Portland now, Thurs night. I will stop at Troutdale Chevron at 10 a.m.. I will wait 15 minutes and if no one is there, then I will head for the Show at the fairgrounds in Washington. My phone is 415 290-8793. Take care, Bob
