    Out of chevy brake troubleshooting ideas

    thanks broncnaz.. just checked and the ring has turned on the spindle a bit.. I disassembled everything and i can see where the keyway on the ring has eaten away some of the threads on the spindle.

    Out of chevy brake troubleshooting ideas

    just got done swapping the rotors, now it pulls to the right. Swapped pads just to double check and still pulls right after the rotor swap. Hoping this is the problem. Will report back if the new rotor fixes it.. I noted in my last post that the outer bearing nut on the right side was only...

    Astro Proportioning Valve?

    I didn’t use the Astro prop valve. But i recall that the lines for the rear brakes from the MC to the prop valve and the valve to the rear were ¼ inch. The brake line on bronco to the rear is 3/16.. so you'd have to use a union to go from 1/4 to 3/16. When I did mine a year ago, I used the...

    Out of chevy brake troubleshooting ideas

    Thanks for the ideas....Here’s what we did tonight. Plugged the rear hard line on the frame rail with a cap and took it for a drive. Brakes funny with no rear brakes, but still pulls left with the same force. Concluding rear brakes not the cause Put the front end on jack stands and check...

    Out of chevy brake troubleshooting ideas

    We took off the hardlines on the axle and put on new lines w/ some very soft "S" curves to ensure we didn't have any kinks that were causing the pull.. the new lines didn't change anything so we put the old ones back on. Maybe the connection from the frame to axle soft line that branches to...

    Out of chevy brake troubleshooting ideas

    Helping a friend with his new chevy brake conversion. Normal braking is great, but going faster or slamming on the brakes causes it to pull to the left. Last winter it got new steering linkages, bushings, ball joints. Everything is new on the brakes except the prop valve, the spindles and...

    Rear Spring Sag

    I pulled the front end this morning, the radius arms are parellel. With the front part of frame on jack stands there is no lean i can see from the front, the rear left is still sagging w/ no radius arms installed. I dont think its being cause by the front end

    Rear Spring Sag

    With my old springs, the rear left leaned about 1.5 inches when looking at it from the rear. The front is only off 1/4 inch. My neighbor and I both bought new suspensions (dever springs/ BC coils) this last month. We did mine first, and after a day it was leaning again in the rear and only a...

    Disks pulling

    Finally got the problem solved.. I'm still in a bit of disbelief here but it turned out to be a difference between the rotors. By chance I noticed the one rotor had a metric reading for min thickness and the other was in inches. I drove it to Napa so they could look and they confirmed...

    Disks pulling

    Borrowed a pressure gauge this am. Turns out it's the caliper. I moved the L-caliper over just to double check. I hooked it up to the right side and used an old rotor and the pressure and pressure time were the same. As of this am i've made two trips to different Napas to pick up a new...

    Disks pulling

    more testing. I pulled both calipers and pushed the pistons in, then applied the brakes. the drivers side certinaly has more fluid moving through it. Put the calipers back on, pumped up the brakes to and cracked the bleeders again, this time, nothing came out of the bleeder on the...

    Disks pulling

    sorry for length..... Before my hydro install, my brakes would pull hard to the driver side during panic stops. When I did my hydro install, I got bored and pulled the front end, replaced all the bushings, tire rods, ball joints, steering, as well as all the brake hardware (calipers, rotors...

    Nose dive with brakes..engine cuts out

    I checked the floats, fuel from the secondary bowl drained out of the sight window when i opened it, i'm pretty sure that had to be the problem.. thanks for pointing me in the right direction..

    Nose dive with brakes..engine cuts out

    I'll go back and check the fuel level and the electrical connections again. Thinking about it more, this happened a few years back in the snow; when i'd rev the motor to get over snow drifts the truck would bounce and the engine would die. It's a 72, i put the 4x4x2 PS and saginaw pump on it...

    Nose dive with brakes..engine cuts out

    idle speed was 600rpm, i bumped it a bit and I ran it again and the engine died the first time i slammed on the brakes.. With the hood open, i did notice that when i hit the brakes hard the PS belt jumps up a few inches before the pulley, not sure if that's normal for hydroboost or if that...

    Nose dive with brakes..engine cuts out

    Finally got my hydroboost installed and it's wonderful to be able to stop like a new car.. ;D I took it out this evening for a test run and try some more panic stops. Both times I panic stopped the nose dives down hard and the engine cut both times. :o Any ideas on why the engine is...

    Astro Hydro low pressure size

    i had to go overseas at the last min (and was about 10min more work away from finally driving it after a years worth of work.) Don't trust the wife to pull the fitting so I was hoping someone here knew so i could have the her pick it up.

    Astro Hydro low pressure size

    Does anyone know the thread size of the low pressure nipple on the Astrovan. I need to see if I can find 90degree fitting for the return line since I mounted it upside down and the return line is kinked. Thanks
