Ok I have a 53 Chevrolet sedan and I pulled it out of the garage the other day hit the brakes and the pedal hit the floor it did pump back up but hit the floor soon after so I find the master Cylinder low so I fill it up bleed the system and hit the road everything seems good made some noise from the front and I could feel a t******* in the brake pedal but went away shortly after driving a bit then today I go for a spin now the pedals is sloppy not as bad as before but pretty bad no leaks that I could find any ideas
if the m/c was low there has to be a leak somewhere---check the rubber line at rear end 1st then wheel cyl -hoses at both wheels and then check the m/c
Pull all 4 wheels and do a complete inspection. If the fluid was low it had to go somewhere. Check the pushrod end of the master for leak. Pull back the dust boots on each wheel cylinder and check for leak. If fluid drips out, need to overhaul or replace the wheel cylinders
Its just strange I dont see any leaks ill have to inspect more do you think maybe the mc is bad it looks like the oem and its kinda rough looking
Never depend on your brakes after hearing or feeling a "t*******"...leaking or not. Take off the wheels and drums as BobMcD suggested. You probably have a loose shoe. Sounds like the MS needs to be rebuilt or replaced also. They can leak internally with no external leaks. Pretty simple and inexpensive to do. Take it apart, hone the bore, new rubber seals.
The thump never stays long ive racked my brain as to what it could be ive had the front end apart looking at things nothing seems out of the ordinary but them again im no mechanic
Oh...you've had the drums off, but didn't see anything? Hmmm...take another look and check to see if the pins that secure the brakes to the backing plates are present. They go through the shoes and the backing plates with little round locks on the end at the shoes. Don't just look...pull on the shoes...make sure they're secure. One possibility...if the brake material on the shoe is thin and/or the drums have been machined past their safe limit, and/or the brakes aren't adjusted well enough, there could be too much space between the shoes and the drum. When the brake is applied, one shoe might be grabbing...catching, and being intermittently forced out of position. Loosely adjusted brakes can add to the low pedal issue too.
Ok ill take a look could my problem be maybe fluid not returning and leaving one side of the brake engaged until I work the pedal some
