  1. After contacting Peninsula Auto re: the wrong part, they quickly sent out the correct hose.  All four flexible brake hoses have now been replace.  Note to all;  this was a 1973 TR6 with the original brake lines.  The inside diameter of the hose had collapsed and I suspect this is deterioration over time, and may well be occurring on similar and older vintages.  If your wheels aren't spinning freely after hard braking, this may be a good spot to consider.

    Thanks to all whom contributed.  Problem solved.

    Hello Stuart;

    I don't suppose you have a close up of the 3 way block for the rear left flexi-line brake hose?  The parts supplier has given me two identical hoses but the left side is supposed to have a raised cylinder boss.  I'm wondering if I can jury rig it with washers or does it fit inside the three-way.

  3. So I got behind the rear wheels to take a look at both L & R flex hoses currently on the car and they appear to be the same length (8").  Further, the threads on the fittings on all 4 ends are all the same (3/8 UNF?).  Same length, same thread and to my eye, interchangeable.  As such, I'm still puzzled as to why they are different part numbers.

    Hi,

    in the UK, Moss no longer do the standard flex hoses. They now show TT3242 as a kit of two hoses. It appears they are the same left & right.

    The hoses on the car look identical too (rear: right and left).  But if I was to order them individually, I would need two different parts numbers.

  5. I bought three new flexible brake hoses to replace the front and back flex lines in the TR6 (front drive side had already been done).  Parts guy at Peninsula Auto (Toronto) says the right and left rear ones are different.  I didn't realize this.

    On installing front right hose, the one he had sold me (at an extortion rate for an 'made - in - India' knockoff) didn't fit.  The purchased hose was 8" long with the two 1" fittings no the end; total length 10".  The length required for the front end is 12" total length.  

    Perhaps he's mislabeled them, thinks I.  Sure enough, one of the hoses labeled for the rear is the correct length and diameter for the front.  Front end now sorted.

    However, now I'm left with two identical rear hoses, both with 8" hose length and the 1" fittings on the ends.

    The question; what is the difference between the right and left rear flexi-brake hoses?

    Thoughts, opinions welcome.

     

  6. A few weeks ago, I posted an issue here that had me rather baffled.  The front driver side would tended to dive in on braking and the wheel on the opposite side would not spin free following hard braking  (observed while on the hoist).  I had many helpful suggestions; brake pad differences, calliper seized, flexible brake tube 'ballooning' and then there was the possibly it was a suspension bushing issue rather than the brakes.

    Remarkably (or not) it was two issues; the flexible tubes were indeed bunged up and not releasing the pressure on the brake pads.  The tubes were acting as a check valve, which in turn was causing excessive forces on the suspension bushings, which had almost completely failed on the driver side.

    So, thanks all.  The knowledge found on this site has proved to be invaluable once again.

    Happy motoring.

    it might not be brakes. Could be a worn wishbone bush or ball-joint allowing the left wheel to assume the wrong toe-in.

    Peter

    I replaced the upper wishbone bushings last year and just had a look at them.  They have deteriorated and are falling apart at the upper wishbone arm.  Most likely part of the problem.  Warning to all: don't buy el-cheapo eBay components.  You get what you pay for.

    If you've cleaned it up and got the pads free, have you taken it for a test drive? Might be worth getting someone to press the pedal and see if the wheel locks up on both sides while it's jacked up. 

    Also the pads could be contaminated, check the surface carefully or perhaps glazed.

    Gareth

    Yes, did that too. Had all four wheels up on blocks and tested the brakes;  good all around.  When released, all wheels spin freely except for front right which was binding.  Took out pads, inspected disk (clean & clear) and replaced; issue persists.  Removed calliper, popped pistons out, cleaned and cleared all channels, re-installed, bleed the brakes then test drive.  While the pistons were out, I removed the seal and checked for clearance between calliper an and piston and it seems ok (moves freely).

    Subsequent test drive reveals same pulling to left, though not as severe.  Back home and on the lift again and the binding is still evident on right side.  As you note and I agree, this would point to a right side issue.  But why isn't the piston easing or the pressure releasing.  (I'll open the bleed valve once seized to see if that corrects it, pointing to a piston issue rather than brake fluid pressure)

    Rob H suspects flex hose 'ballooning" and I'll check that next time I can get my trusty assistant to help but I'm at the point now where I'm thinking both callipers should be replaced.

    Probably not with fingers, a spanner/bar yes. 

    Maybe compare sides so you can feel how easy it is one side compared to the other. 

    Make sure the pads can move when fitted too and are not binding. Refit and use the pedal to push the pistons back onto the disk, you may need to work the piston in and out a few times. 

    Did you notice the right side disk was either rusty (little to no contact) or blue (where it's been binding and got hot)? 

    Gareth

    Both disks look are clean and rust free.  But the pads a definitely harder to remove on the right (binding) side.  I took the caliper off and gave it a good clean.  All channels are clear and the pistons will move freely in the caliper with the seal removed; that is clearance appears okay.

    To add another element, I replaced internal component of the valve assembly last year with no evident issues.  This new braking issue has surfaced this spring.

    I feel this is a solvable problem and really don't want to take it to a shop for repair.

    Start by removing the pads from the RH side and clean the surfaces, it maybe just a build up of dirt. See if you can push the pistons back a little in case one is seized. But you may find it is just brake dust etc.

     

    Rob

    Thanks Rob; I've already done that.  I'm not sure how much pressure must be applied to push the pistons back.  Should I be able to do this with finger pressure?  If so, this is not the case.

  11. I'm sure this has been covered on other topic strings but my 73 TR6 pulls hard to the left side on braking.  I've bled the brakes all around and looked for leaks; all appears good.  Reservoir at nominal level, pads and callipers look okay.  

    The odd thing on top of the imbalanced braking is that it is the right side wheel that seems to be binding a bit after a drive (and I've got it on the lift). So on braking, it pulls to the left but on the lift, the rights side front seems to be binding a bit.   

    Any suggestions as to which component may be at fault would be appreciated.  I'm not sure of where to start.

    Thanks

  12. I'm refitting the brake caliper seals in the TR6 and should have paid closer attention while dissembling.  I've notice the cross-section profile of the ring gasket has one higher inside diameter edge rather than a straight forward rectangular shape; that is it has a peak on one side.   I'm thinking the higher edge goes toward the outer side of the caliper, toward the brake fluid pressure, with the lower edge permitting in and out movement.  

    Have I got this correct?

    Thanks
