GEO PRIZM BRAKES PROBLEM

1990 Geo Prizm • 120,000 miles

Need help! My 90 geo prizm LSI got flooded by hurricane Sandy.I live next to the chesapeake bay which put the back half of the car under salt water. Just the back brakes and drums. Could not get back to the house due to high water. By the time I cleaned up and got back to the car, the back brakes rusted up so bad I can't get them apart. I've soaked them and pounded on them, NO luck. A freind gave me a parts car which is a 90 geo prizm 4dr sedan GSI. It has disc brakes on the back. I beat on my car so badly I need to change eyerything. Finally here is the questions. My parts car has no hubs on it. Are the hubs the same on drum set-up as they are with disc or are they different lengths?I know the proportion valve is different I have one of those and also a master cylinder. My parts car had an engine fire so I don't know if the brake lines are the same they were melted away.I can't locate this type of car in the state of maryland. Hate to trash this car, has new motor and rebuilt trans. My parts car has new rear struts and the trailing arms look perfect. Just want to change everything over if possible? Can I do this and what will I need. Or should I get some wood, gas and make a big fire? THANKS for any help you can did me! Ron,

Ok, the hubs are different part numbers so I assume they are different. The lines are ok to use if you have the room and can safely bend them.

Change the valve and master.

As far as the rest, any wiring back there should be replaced. Salt water flooding is a death kill for metal and electric.

Good luck.

If you wish to change the rear arms etc, that is possible but the handbrake cables etc would have to be transplanted as well.

Disc and drum do not mix so complete assy has to be transferred. The brake hoses too.

OK, The car was parked on a hill, got the engine as high as possible. Only got 2-3 inches of water in spare tire well. Did not reach the tail lights or any wiring at all. Got in the drums, tire well, parking brake cables, muffler. Put a lawn sprinkler under it for an hour to wash it out as good as possible. Parts car has everything in the back I need but no hubs. Do you have the part number I need? Also is it a GM part or a Toyota part? The only thing I question is the brake lines off the master cylinder. I have a shop manual that has a drawn picture of the proportion valve of a GSI and one of the lines is bent in a different way then mine. I wish I could get a diagram for it if possible. The valve is the same as the one on my car and so is the master cylinder. All the fittings are in the same place and same size. Looks like a plug and play to me, hope it is. The only problem is finding the hubs. Thank you guys very much for your help! Ron.

The brake components should be a plug and play type so no problem with that. Sometimes the pipes might be bent differently due to the model year for the master cylinder If you need to reroute ths pipe, do it gently by making curves gentle and notbending it too acutely.

You should try the salvage yard for the hub which would be much cheaper than getting new sets. Toyota or GM both should be applicable but sorry I don't have the part/no for you.

I was looking for the part number as well and came up with nothing. Not a popular option.

Call around to junk yards before visiting.

I installed wheel dollies under both wheels and drove it in my garage and I am going to start on this. Any ideas what cars are interchangable with the 90 prizm? I know that 88-92 prizm hubs work on this car.[ But that is for drum brakes]. I guess the same year corollas work also? I know the amount of time I spent in the boneyards in maryland I'am not going to find it used. Hopefully I can get it new. I know I will have to bite the bullitt on this one.

The Corollas shouls work and if I am not wrong, up to 96 models might match.
