  1. Hi Rabin - I can verify 100% certain both front brakes are binding/hanging/braking. I do not know if Tim bench bled the MC. I will ask him. I do know both times he bled the brakes he used a power bleeder. We put on new rubber brake lines as part of the brake service. I had a spongy pedal before this all started. A very bad pedal but the car still stopped. Brian Holm identified that the master cylinder (which was newish) was wrong and was for a sedan. Then Tim found a weeping LR wheel cylinder which was replaced. As mentioned when those parts were installed I had a *perfect* pedal. Thanks for your continued help and suggestions. Rudy
  2. Rabin - I pulled the vacuum line off the booster (left the hose attached to the air box) and plugged it will a bolt and tightened it with a #4 hose clamp. Took it for a test run and the brakes started hanging up again. My quick fix is to pull up on the e-brake which immediately reduces the drag but the problem eventually comes back. Do you think it could be the proportioning valve acting? I heard they can get funky being so old and to replace them with a "T" to bypass the prop valve's function. My tech says that the prop valve controls the rear brakes only. I think he may be wrong. Still do not know if bleeding the brakes with all 4 wheels on the ground is for sedans only (4 wheel disc) of if that pertains to wagons as well. I certainly appreciate your suggestion. Has anyone else had this problem? Or know of a remedy? Thanks!! Rudy
  3. Thanks so much Rabin. Will try your suggestion this weekend and report back how it works out. 👍
  4. Hello - Greetings. New member here. Some quick background: Purchased my first Peugeot from a French car enthusiast in TN and recently had my mechanic sort the car (complete tune-up/timing belt/valve adjustment/LR wheel cylinder/master cylinder/etc.). It is a 1988 505 DL wagon according the window sticker but says GL on the rear door and came with a GL supplement with the owner's manual. Normally aspirated. Automatic transmission. Original paint. No rust. 164K miles. Excellent original interior. Stacks of receipts. Lot's to like. Here is the issue and we are lost.... When I got the car it had a low brake pedal. Brian Holm said that the newish master cylinder on the car was for a sedan. My mechanic Tim discovered a leaking LR wheel cylinder and a fluid soaked LR brake shoe. So I ordered a wagon master cylinder and wheel cylinder from Brian. When the new master and wheel cylinder was installed I had a great pedal. Perfect. I took the car for a 10 mile drive before he tackled the rest and noticed the brakes got tight. The car was being held back. I parked on a grade by Tim's shop and it stayed on the hill in neutral without touching the brakes. Tim thought it was the brake shoe that was doused in brake fluid that was the culprit. He cleaned it up again and readjusted the brakes. Fast forward this Friday Tim calls me to say the car is ready but he took it for a test drive and the front brakes are holding the car back. Both are tight. He said he power flushed the brake system again. I re-mentioned to him a process where you can't jack the car up when bleeding the brakes but I could not remember the exact details. I swore I read it somewhere over the years. I suggested he call Brian. Tim told me Brian said to bled the brakes again and that the right front is notoriously hard to bleed. I drove the car home (15 miles) without issue until I took the family for a ride. Steering wheel shaking. Brake pedal getting stiff. Both front wheels were smoking when I got it home. I checked things out on this awesome website and did some research and found Bean (Rabin) mentioned about not having the wheels hang when bleeding the brakes (at least on a sedan). I texted TIm as he has both kinds of lifts in his shop and he said they were hanging when he bled them. Darn it! Just don't' know if this pertains to wagons since they have drums in the rear??? It gets weirder... Yesterday I took the car out again with a perfect pedal upon start up and within a couple miles the steering wheel was shaking and the brake pedal was getting hard. Got it back home and opened the hood and poked around the large cloth covered vacuum line behind the maser cylinder that runs to the booster. My brakes were fine again. Another quick trip they were locking up again. This time I picked up on the e-brake handle and quickly released it. My front brakes were fine! My brake pedal was perfect. Went for another quick trip around the block. The same thing happened. This time I put it on a slight grade rolling backwards with the car in neutral with the e-brake off. The car sat still and did not roll backwards until I lifted and released the e-brake handle then it coasted effortlessly backwards. Repeated this two more times with drives around the neighborhood. NOTE: I may have pulled the e-brake before I got out of the car the first time to inspect the vacuum line and master cylinder under the hood but am not 100% sure. My buddy in IN who used to have Peugeots contacted his 90 year old Peugeot mechanic and the gentleman said it's probably the brake booster check valve. That they stick. My mechanic Tim thinks it's either the wrong or defective master cylinder or the brake booster. I mentioned the proportioning valve that I read on here that can get out of whack with time and with improper bleeding and some are replaced with a "T" since they are unobtanium. Tim says the proportioning valve is only for the rear brakes. So what do you think? Master cylinder? Power Booster? Check Valve in the Power Booster? Proportioning Valve? Why would the e-brake which controls the rear brakes have anything to do with unsticking stuck front brakes? I'm at a loss. Hate to throw parts at this needlessly. If you have any ideas on how to diagnose or remedy this problem it would be greatly appreciated. Love to get the car to the Pittsburgh Vintage Grand Prix in 2 weeks but unless it's something simple it probably will be next year. Thanks for any help guys! Rudy in Pittsburgh
