Right now it is 1 degree above zero, with today being the coldest for the next week or so; after today high to low will bounce from approx. 0 to 20 above.
I was heading out the other day when I found I had zero brakes , on my 1978 Oldsmobile Delta 88, fortunately no cars were coming as I was on a steep alley hill and no way to stop plus I did not want to drive into a snow bank.
I am glad I did not find this out 30 miles out in the boonies.
Emergency , unless you are five feet tall tisn't easy to get your foot on and the handle to release is worse, but I drove it to the repair shop with one hand on the release and the other on the E-brake.
(Third time in my life I have had this happen on a moving automobile.)
I did find out that it is probably a good idea to do that just to keep them loose and unstuck, as one-half mile down the road the brake pedal was far easier to depress.
Original estimate on my 1978 Oldsmobile Delta 88 was 1,200 dollars for new master cylinder, that was what was shot, and ALL NEW brake calipers as he could not break the bleed screws open on the wheel cylinders.
Fortunately, again, he had a new tool to apply heat to stuck screws and bolts and got them open, so final bill 396 dollars.
I checked on prices for new/rebuilt master cylinders, minus shipping and they varied from $30 new to $80 rebuilt.
I have put them in before but in this weather , I am not going stand outside in single digit weather with bare hands, and you will end up taking your gloves off.
BUT
He found out the Proportioning valve was shot, SO, I bought new one at JEGG"S auto store, online (NO store in town had one) for , with shipping 61 dollars.
Now I can spend an extra 70 dollars and have them put it in or do it my self, BUT the brakes will need bleading again, while that is a pain in the buttocks in the summer, in this weather, which comes first, mone or misery?
The mechanic, who has done a LOT for me for free or reduced prices in 20 years, said he thinks the Proportioning valve has not been working for a long time and maybe neve, so I have been using only my front brakes as long as I had the car.
I will be installing new pads and shoes, my self when weather warms up.
