Braking issue...fixed pics
« on: January 23, 2016, 09:16:40 PM »
I've had the same problem for a while now and I just. Checked all pads and hoses 3 days ago so I guess I'm gonna start with re bleeding the left driver's side and go from there. I've never gotten the dummy brake light but it could be broke or disconnected. The PV is the same one since '87 so we will see. I will post any progress as well if you wish since it is your thread Usareke

Here's a little idea of how bad it is. This is at roughly 30mph.

Did a little skid testing too. This view is from front looking back to where I started braking.

And vice versa.

Have you replaced  the flex hoses on the front ?

They clog up inside

I did both hoses in 2013 when I put the lift on. They were part of the i8t

These trucks either stop well or don't stop at all. When they decide to not stop at all its a royal pain in the ass to figure out why and can get expensive fast!

I've replaced every single part of my trucks braking system and it still bloody sucks. I think one of the biggest issues is simply bleeding and doing the 2 person job I don't think cuts it. Gravity bleeding doesn't work well.

Pulling usually ends up being the opposite side of the actual pull in this case if if swings left its the right side which means you probably have caliper issues. These 40 year old trucks people never think of rebuilding or replacing calipers... so check those.

the rear drum brakes on  just about any vehicle require a manual adjustment from time to time - and oddly enough it seems the drivers side rear is always out a little more than the opposite side ????   if you took your vehicle to a  garage for oil changes the brake adjustment would always be done then .

Make sure the calipers are moving freely. If so replace the left side hose.

May have found part if not all of the issue. Both pin-bolts on the driver's side have a slight bend to them. This may be causing the initial catch and once I apply enough pressure everything seems better. Going to look for new bolts hopefully this afternoon. Dorman makes a pin-bolt and guide sleeve kit for $15. Either way these need to be replaced so I'm not replacing needless parts if it does end up being the caliper

You can buy the whole caliper for under $15
